August 3, 2023Hsslive.net provided Plus One Chemistry notes for students in their higher secondary years in two languages English Medium & Malayalam Medium. Topics- “Law of Chemical Combination” that are usually covered in the first year of chemistry at the higher secondary levelTable of ContentsLaws of Chemical CombinationsLaw of Conservation of Mass:Law of Definite Proportions:Law of Multiple Proportions:Law of Reciprocal Proportions: Laws of Chemical Combinations The rules for how different elements can be put together to make compounds are called the laws of chemistry combinations. They are based on what experts who have studied the nature and behavior’s of matter have seen and done. These rules help us understand the composition and properties of compounds, as well as the stoichiometry and conservation of mass in chemical reactions. In this chapter, we will learn about four rules. These are: Law of Conservation of Mass: This law says that during a chemical reaction, matter can neither be made nor removed. In other words, in a chemical process, the total mass of the reactants is the same as the total mass of the products. In 1789, Antoine Lavoisier came up with this law and did a number of experiments to show it. He showed, for example, that when mercury oxide is burned, it breaks down into mercury and oxygen, and the amount of mercury and oxygen is the same as the amount of mercury oxide. !Mercury oxide decomposition) We can do a simple experiment with a closed system, like a sealed flask or a balloon, to test this rule. We can burn a known amount of a fuel, like a strip of magnesium, in air or oxygen. Then, we can measure the mass of the result, like magnesium oxide, and compare it to the mass of the reactant at the beginning. As shown below, we will find that there is no change in mass. !Magnesium burning) Law of Definite Proportions: This law says that a given compound always has the same parts in the same fixed mass ratio, no matter where it came from or how it was made. For example, water always has 1 part hydrogen to 8 parts oxygen by mass. In 1799, Joseph Proust came up with this law and did several experiments to show it. For instance, he showed that the amount of copper, carbon, and oxygen in copper carbonate is always 5:2:3 by mass. !Copper carbonate) To test this rule, we can do a simple experiment in which we use a known amount of a compound, like sodium chloride, and use electricity to separate its parts. Then we can measure how much sodium and chlorine were made and compare them to how much sodium chloride there was to start with. As shown below, we will find that they are in a set ratio. !Sodium chloride electrolysis) Law of Multiple Proportions: This law says that when two elements combine to make more than one compound, the masses of one element that combine with a set mass of the other element are in a simple ratio of whole numbers. Carbon and oxygen, for example, can join to make two different compounds: carbon monoxide (CO) and carbon dioxide (CO2). In each of these molecules, 12 g of carbon combines with either 16 g or 32 g of oxygen. 16:32, or 1:2, is the ratio of the amounts of oxygen that combine with a given amount of carbon. John Dalton came up with this law in 1803. He used it to back up his atomic theory. !Carbon and oxygen compounds) To test this rule, we can do a simple experiment in which we mix a known amount of one element, like nitrogen gas, with different amounts of another element, like hydrogen gas. Then, we can compare the amounts of ammonia (NH3) and hydrazine (N2H4) that were made to the amounts of nitrogen and hydrogen that were used at the beginning. As shown below, we will find that they are in a simple ratio. !Nitrogen and hydrogen compounds) Law of Reciprocal Proportions: This law says that when two elements combine separately with a third element, the ratio of the masses in which they do so is either the same as or a simple multiple of the ratio in which they combine with each other. For example, hydrogen and oxygen can each join with nitrogen to make ammonia (NH3) and nitric oxide (NO), respectively. In these molecules, 14 grammes of nitrogen are mixed with 3 grammes of hydrogen and 8 grammes of oxygen. When hydrogen and oxygen combine with a set amount of nitrogen, the ratio of their masses is 3:8. This is the same number of hydrogen atoms and oxygen atoms that come together to make water. In 1792, Jeremias Richter came up with this rule. He used it to study how salts are made. !Hydrogen and oxygen compounds) To test this rule, we can do a simple experiment with a known mass of one element, like carbon, and different masses of another element, like chlorine, that react with it separately. Then, we can compare the amounts of carbon tetrachloride (CCl4) and carbon monochloride (CCl) that were made to the amounts of carbon and chlorine that were used in the beginning. We will find that they are in a simple multiple of the ratio of how much carbon and chlorine are needed to make carbon dichloride (CCl2), as shown below. !Carbon and chlorine compounds) In this chapter, we’ve learned the four rules of chemical combinations. They help us understand the parts and properties of compounds, as well as the stoichiometry and conservation of mass in chemical processes.

August 3, 2023Higher Secondary Plus One Chemistry Notes for Kerala Board Syllabus. It’s a fascinating subject that helps us understand the world around us at a molecular level. Hsslive.net provided Plus One Chemistry notes for students. Topics- “Some Basic Concepts of Chemistry” that are usually covered in the first year of chemistry at the higher secondary level. valuable for both Kerala Syllabus and CBSE students with knowledge cultivated over two decades of teaching experience.Table of ContentsSome Basic Concepts of ChemistryThe International System of Units (SI)Atomic Mass, Molecular Mass, Formula Mass, and Molar MassLaws of Chemical CombinationThe Mole ConceptConcentration of Solutions Some Basic Concepts of Chemistry Chemistry is the study of matter and the changes it can undergo. Matter is anything that has mass and occupies space. Matter can be classified into different types based on its physical state (solid, liquid, or gas), composition (element, compound, or mixture), and properties (physical or chemical). Some basic concepts of chemistry that we will learn in this chapter are:The International System of Units (SI) and the rules for using them. The concepts of atomic mass, molecular mass, formula mass, and molar mass. The laws of chemical combination and their applications. The mole concept and its relation to mass, volume, and number of particles. The methods of expressing concentration of solutions. The calculations involving stoichiometry and limiting reagents.The International System of Units (SI) The International System of Units (SI) is a standard system of measurement that is widely used in science and engineering. It consists of seven base units and several derived units. The base units are:Metre (m) for length Kilogram (kg) for mass Second (s) for time Ampere (A) for electric current Kelvin (K) for temperature Mole (mol) for amount of substance Candela (cd) for luminous intensityThe derived units are obtained by combining the base units with appropriate prefixes and exponents. For example, the unit of force is newton (N), which is defined as kg m s-2. Some rules for using the SI units are:Use a decimal point as the separator for fractional parts of a number. Use a space to separate the digits into groups of three, starting from the decimal point. Do not use commas or spaces within a number. Use a space to separate the number and the unit symbol. Do not use a period after the unit symbol unless it ends a sentence. Use capital letters for unit symbols derived from proper names, such as N for newton or K for kelvin. Use lowercase letters for unit symbols derived from common names, such as m for metre or s for second. Do not use plural forms or hyphens for unit symbols, such as ms for milliseconds or kg-m for kilogram-metre.Atomic Mass, Molecular Mass, Formula Mass, and Molar Mass The atomic mass of an any element is the average mass of its atoms relative to one-twelfth of the mass of a carbon-12 atom. It is called in atomic mass units (u), where 1 u = 1.66 x 10-27 kg. The atomic masses of different elements can be found in the periodic table. The molecular mass of a any compound is the sum of the atomic masses of all the atoms in one molecule of the compound. It is also called in atomic mass units (u). For example, the molecular mass of water (H2O) is 2 x 1.008 u + 16.00 u = 18.016 u. The formula mass of an ionic compounds is the sum of the atomic masses of all the ions present in one formula unit of the compound. It is also expressed in atomic mass units (u). For example, the formula mass of sodium chloride (NaCl) is 22.99 u + 35.45 u = 58.44 u. The molar mass of a any substance is the mass of one mole of that substance. It is expressed in grams per mole (g mol-1). One mole of a substance contains 6.022 x 1023 particles (atoms, molecules, or ions) of that substance. This number is called Avogadro’s constant (NA). The molar mass of a substance is equal to its atomic mass, molecular mass, or formula mass in grams. For example, the molar mass of water is 18.016 g mol-1 and the molar mass of sodium chloride is 58.44 g mol-1. Laws of Chemical Combination There are four laws that govern the combination of different elements to form compounds. They are:Law of Conservation Of Mass: This law states that matter can neither be created nor destroyed in a chemical reactionyouca, n also say that total mass of the reactants is equal to the total mass of the final products in a chemical reaction. Law of Definite Proportions: This law states that a given compound always contains the same elements in the same fixed ratio by mass, regardless of its source or method of preparation. For example, water always contains hydrogen and oxygen in the ratio 1:8 by mass. Law of Multiple Proportions: This law states that when two elements combine to form more than one compound, the masses of one element that combine with a fixed mass of the other element are in a simple ratio of whole numbers. For example, carbon and oxygen can combine to form two compounds: carbon monoxide (CO) and carbon dioxide (CO2). In these compounds, 12 g of carbon combine with 16 g and 32 g of oxygen, respectively. The ratio of the masses of oxygen that combine with a fixed mass of carbon is 16:32 or 1:2. Law of Reciprocal Proportions: This law states that when two elements combine separately with a third element, the ratio of the masses in which they do so is either the same or a simple multiple of the ratio in which they combine with each other. For example, hydrogen and oxygen can combine separately with nitrogen to form ammonia (NH3) and nitric oxide (NO), respectively. In these compounds, 14 g of nitrogen combine with 3 g and 8 g of hydrogen and oxygen, respectively. The ratio of the masses of hydrogen and oxygen that combined with a fixed mass of nitrogen is 3:8. This is the same as the ratio in which hydrogen and oxygen combine with each other to form water.The Mole Concept The mole concept is a convenient way of expressing the amount of a substance in terms of its particles. One mole of a substance is defined as the amount that contains as many particles as there are atoms in 12 g of carbon-12. This number is equal to Avogadro’s constant (NA), which is 6.022 x 1023. The mole concept can be used to relate the mass, volume, and number of particles of a substance.Mass-Mole Relationship: The mass-mole relationship is based on the molar mass of a any substance, which is the mass of one mole of that substance. The molar mass can be calculated by multiplying the atomic mass, molecular mass, or formula mass by NA. The mass-mole relationship can be expressed as: Mass (g) = Number of moles (mol) x Molar mass (g mol-1) For example, to calculate the mass of 2 moles of water, we use the formula: Mass (g) = 2 mol x 18.016 g mol-1 = 36.032 g Volume-Mole Relationship: The volume-mole relationship is based on the molar volume of a gas, which is the volume occupied by one mole of any gas at standard temperature and pressure (STP). STP is defined as 0°C (273 K) and 1 atm (101.3 kPa). The molar volume of any gas at STP is 22.4 L mol-1. The volume-mole relationship can be expressed as: Volume (L) = Number of moles (mol) x Molar volume (L mol-1) For example, to calculate the volume occupied by 0.5 moles of oxygen gas at STP, we use the formula: Volume (L) = 0.5 mol x 22.4 L mol-1 = 11.2 L Particle-Mole Relationship: The particle-mole relationship is based on Avogadro’s constant (NA), which is the number of particles in one mole of a substance. The particles can be atoms, molecules, or ions, depending on the nature of the substance. The particle-mole relationship can be expressed as: Number of particles = Number of moles (mol) x Avogadro’s constant (NA) For example, to calculate the number of molecules in 3 moles of carbon dioxide, we use the formula: Number of molecules = 3 mol x 6.022 x 1023 = 1.807 x 1024Concentration of Solutions A solution is a homogeneous mixture of two or more substances. The substance that dissolves in another substance is called the solute, and the substance that does the dissolved is called the solvent. The concentration of a solution is a measure of how much solute is present in a given amount of solvent or solution. There are different ways of expressing concentration, such as:Mass Percent: Mass % is defined as the mass of solute per 100 g of solution. It can be calculated by this formula: Mass percent (%) = Mass of solute (g) / Mass of solution (g) x 100 For example, to calculate the mass percent of sodium chloride in a solution containing 5 g  [...]Read more...
August 3, 2023Hsslive.net provided Plus One Chemistry notes for students in their higher secondary years in two languages English Medium & Malayalam Medium. Topics- “Importance of Chemistry” that are usually covered in the first year of chemistry at the higher secondary level. valuable for both Kerala Syllabus and CBSE students with knowledge cultivated over two decades of teaching experience. Importance of Chemistry 1. Matter and Its Classification Matter, the substance that occupies space and possesses mass, is classified into three states: solid, liquid, and gas. For example:Ice (solid) – H2O in a solid state Water (liquid) – H2O in a liquid state Water vapor (gas) – H2O in a gaseous state2. Laws of Chemical Combinations Chemical reactions follow well-defined laws, which include: a) Law of Conservation of Mass: The total mass of substances in a chemical reaction remains constant, indicating that atoms are neither created nor destroyed during the process. Example: When hydrogen (H2) reacts with oxygen (O2) to form water (H2O), the total mass of reactants (H2 + O2) is equal to the total mass of products (H2O). b) Law of Definite Proportions: Elements combine in fixed mass ratios to form compounds, leading to their unique identities. Example: Water (H2O) always has a fixed mass ratio of hydrogen and oxygen, regardless of its source. c) Law of Multiple Proportions: When two elements form more than one compound, the ratios of masses of one element to a fixed mass of the other element are in small whole numbers. Example: Carbon and oxygen can form two compounds: carbon monoxide (CO) and carbon dioxide (CO2). The mass ratio of oxygen to carbon in CO2 is twice that of CO. 3. Atomic and Molecular Mass Understanding the atomic and molecular masses is vital in quantifying substances’ amount in chemical reactions. The atomic mass unit (amu) is used to express these masses relative to the carbon-12 isotope. Example: The atomic mass of carbon is 12.011 amu, while the molecular mass of water (H2O) is (2×1.008 amu) + 16.00 amu = 18.016 amu. 4. Mole Concept The mole concept bridges the macroscopic and microscopic worlds by connecting mass, number of particles, and Avogadro’s number (6.022 x 10^23). It enables easy conversions between mass, moles, and particles. Example: One mole of any substance contains Avogadro’s number of particles, which is approximately 6.022 x 10^23. Therefore, one mole of atoms of an element has a mass equal to its atomic mass in grams. Numerical Example: Calculate the number of moles in 60 grams of carbon dioxide (CO2). Solution: Molar mass of CO2 = (12.01 g/mol + 2×16.00 g/mol) = 44.01 g/mol Number of moles = Mass of CO2 / Molar mass of CO2 Number of moles = 60 g / 44.01 g/mol ≈ 1.36 moles [...]Read more...
August 3, 2023Welcome to the captivating world of Chemistry, where we unravel the mysteries of matter – the building blocks of the universe. In this chapter, “Some Basic Concepts of Chemistry – Nature of Matter,” we embark on a journey of exploration to understand the fundamental nature and characteristics of matter. 1. Atomic Structure: The Foundation of Matter At the heart of matter lies the concept of atomic structure. Imagine atoms as tiny, dynamic universes with their subatomic planets. The nucleus, composed of protons and neutrons, anchors the electrons in their orbits. This delicate balance between positive and negative charges governs the behavior of matter at the atomic level. 2. Elements and Compounds: The Diversity of Matter In the realm of Chemistry, matter manifests itself as elements and compounds. Elements are like the unique personalities of the periodic table, with each possessing its distinct identity. On the other hand, compounds are a marriage of different elements, combining their characteristics to create novel substances. For instance, oxygen (O2) is an element, a life-sustaining gas crucial for respiration. However, when two hydrogen atoms join forces with an oxygen atom, they create the remarkable compound, water (H2O), essential for life as we know it. 3. States of Matter: The Ever-Changing Dance Matter is a performer of a beautiful dance, transitioning effortlessly between three states – solid, liquid, and gas. In the solid state, particles are locked in an elegant arrangement, creating distinct shapes and structures. When warmed by energy, matter gracefully transforms into the fluid state of liquids, where particles move with a newfound freedom. Finally, with a surge of energy, matter takes to the stage as a vibrant gas, where particles move unchained and unrestrained. 4. Physical and Chemical Properties: Unraveling the Essence Every substance exhibits its unique personality through physical and chemical properties. Physical properties, like a distinctive fingerprint, can be observed without changing the substance’s composition. These characteristics include color, odor, density, and melting/boiling points. As an analogy, consider a rose – its color, fragrance, and shape are all physical properties that distinguish it from other flowers. Conversely, chemical properties are more like the hidden talents of a performer. They reveal themselves during a chemical reaction when substances interact to form new compounds. These properties define the substance’s reactivity and ability to undergo transformations. Conclusion: Unleashing the Marvels of Matter As we conclude our journey into the “Nature of Matter,” I encourage you to cherish the beauty of Chemistry’s foundational concepts. Embrace the wonders of atomic structure, elements, compounds, and states of matter, for they hold the keys to unraveling the secrets of our universe. [...]Read more...
August 3, 2023So will IIT JEE is tough and it is not easy to score well if you are not following the discipline the time table the structure of course your Physical health and of course your mental health but I want to remind each one of you giving this examination that no matter who you are no matter where you from if you follow the tips that is being told you in this article you will definitely make it and make it big.Table of ContentsWhat is IIT JEE? What its importance? What things an average student should keep in mind while preparing for IIT JEE exam, so that his preparation can be good and mistakes are less?Start Preparing at the right time:-Understand the Syllabus well:-Keep in mind the marks and Weightage:-Select the High Study Material:-Have a Proper Time Management:- What is IIT JEE? What its importance? IIT JEE Indian Institute of Technology is the dream destination of those students who wants to advance in engineering and technology education because of such a world class educational platform which comes provider of quality education and best engineering education and IIT Delhi work on high positions in India and abroad. If you are doing this, then every student with an interest in technology wants to reach IIT, then it should not be surprising because everyone wants to make a secure and precious career. But what happens by wanting, friends get it only to those who are deserving. And the question is, who is deserving, the one who performs the best at the right time with the right sprite while keeping the right attitude, although you know that every year you understand that lakhs of students. They become a part of this, but they get the victory, if they have A to Z knowledge about it and the name of this exam is IIT JEE National level engineering exam, which has two stages, one is JEE Mains and the other is JEE Advanced. Well, you must know all this about it, yet we are telling you once more, JEE Main is such an exam in which the selected students are eligible for JEE Advanced and those who get selected in JEE Advanced, that race. are the winners of the IITs because after winning this highly tough race, they get admission in IIT, every year IIT conducts JEE to select the best student for 4 years B Tech, B Pharma 5 years B Architecture, Integrated MSc and MTech course. Well, you must have known about what is IIT JEE and its importance, but today again a main reason has been done to tell it to remind you that the competition is very high in this exam, it is very tough, the ignition will not work at all without strategy selection. Chances cannot be made and even if there is no motivation, things will not work, so remember that both your effort and intention should be firm, if you share that your intentions are strong, then in today’s article we will tell you that one How the average student cracks IIT JEE? Let us know,  What things an average student should keep in mind while preparing for IIT JEE exam, so that his preparation can be good and mistakes are less? Start Preparing at the right time:- Suppose your aim is to clear IIT JEE in the first attempt itself but you have to start preparing for it well in advance and if you are doing consistent practice for a long time then you will not face any further problem as your syllabus is also completed. You will get sufficient time to solve your problem sort out and your notes will be well maintained then tell whether it will be easy for you to crack the exam or not. So for this you start preparing for JEE from class 11th itself and if you start preparation before that then it will be easy for you to follow the time management discipline and routine which is the basic requirement to clear this exam. Understand the Syllabus well:- First of all, understand the syllabus well, consider that you do not want to waste much time while preparing, but you cannot do anything without checking the syllabus without understanding it properly, then it will not be the right way for your preparation because preparing for the exam. Before starting, you should know what is coming in the exam, what type of questions will be asked, so understand your syllabus well, keep a copy of it on the study table with you  and after that think of getting ready because many times students skip this major step in a hurry but you will not make such mistake at all. Keep in mind the marks and Weightage:- While studying the syllabus, you have to understand well that how much is the chapter vice weightage because for each chapter the marks release is different and it doesn’t matter how much knowledge you have but this thing is more important for the exam. It is that how well you are covering the syllabus, so focus more on the unit with height weight age and then on the low weight age chapter. Like in JEE Mains,  Physics Optics has 10% weightage, Electronic Devices has 14% weightage while Gravitation has 2% weightage. Similarly, Maths has 15% weightage for Coordinate Geometry and 3% weightage for Mathematical Reasoning. In chemistry, organic compound containing oxygen has 6% weight and surface chemistry has 1% weightage. Over all you have to walk high to low but it does not mean that you should study only high weightage because you have to cover the entire syllabus. Select the High Study Material:- Best preparation for the exam does not mean that you have to read a lot of books. The best study method of the exam is that you should choose the right book and the right study material for your exam, in this NCERT books will prepare your base and subject and topic. According to you, you can refer the reference book so that the chances of getting confused do not increase. Where we tell you the names of the subject wise reference books such as:- Best books for physics are HC Verma’s Concepts of Physics Volume One and Volume Two, Halliday Resnick and Walker Fundamentals of Physics, DC Pandey Understanding Physics, and etc. Best books for maths are R.D Sharma, Exemplar, etc. Best books for chemistry are O.P Aggarwal IIT chemistry, Dr RK Gupta textbook of physical chemistry, etc. Have a Proper Time Management:- Managing the time properly for the preparation of the exam. Time plays a very important role, if you have made your proper time table for the preparation of the exam, then it is very good for you and in that time table you have to see that you give particular time to your particular subject. Give equal time to the subject, not that you are studying your favourite subject mostly. Give some time to your weak subjects also. [...]Read more...

August 3, 2023Hsslive.net provided Plus One Chemistry notes for students in their higher secondary years in two languages English Medium & Malayalam Medium. Topics- “Structure of Atom” that are usually covered in the first year of chemistry at the higher secondary level. valuable for both Kerala Syllabus and CBSE students with knowledge cultivated over two decades of teaching experience.Table of ContentsStructure of AtomThomson’s Model of AtomRutherford’s Model of AtomBohr’s Model of AtomQuantum Mechanical Model of AtomDual Nature of Matter and RadiationPhotoelectric EffectAtomic SpectraDe Broglie’s HypothesisQuantum numbers and orbitals:Aufbau principle, Pauli exclusion principle, and Hund’s rule:Electronic configurations of atoms: Structure of Atom An atom is the smallest unit of matter that retains the identity and properties of an element. An atom comprises three subatomic particles: electrons, protons, and neutrons. Electrons are negatively charged particles that move around the nucleus, which is the atom’s central core. Protons are positively charged particles that are present in the nucleus. Neutrons are neutral particles that are also present in the nucleus. The number of protons in an atom determines its atomic number and its identity as an element. The number of neutrons in an atom determines its mass number and its isotopic variation. The number of electrons in an atom determines its charge and chemical behaviours. The structure of an atom has been a subject of interest and investigation for many scientists since the nineteenth century. Various models and theories have been proposed to explain the nature and behaviour of atoms and their interactions with other atoms and radiation. Some of the important models and theories that we will learn in this chapter are:Thomson’s model of an atom Rutherford’s model of the atom Bohr’s model of atom Quantum mechanical model of atom Dual nature of matter and radiation Photoelectric effect Atomic spectra De Broglie’s hypothesis Heisenberg’s uncertainty principle Quantum numbers and orbitals Aufbau principle, Pauli exclusion principle, and Hund’s rule Electronic configurations of atomsThomson’s Model of Atom Thomson’s model of atoms was proposed by J.J. Thomson in 1898, based on his discovery of electrons using cathode ray tubes. He proposed that an atom is a sphere of positive charge in which electrons are embedded like seeds in a watermelon. He also calculated an electron’s charge-to-mass ratio (e/m) as -1.76 x 108 C g-1. This model could explain the electrical neutrality of atoms, but it failed to explain the results of later experiments, such as the scattering of alpha particles by thin metal foils. ! Thomson’s model) Rutherford’s Model of Atom Rutherford’s model of the atom was proposed by Ernest Rutherford in 1911, based on his famous alpha-particle scattering experiment. He bombarded a thin gold foil with a beam of alpha particles (positively charged helium nuclei) and observed their deflection using a fluorescent screen. He found that most alpha particles passed through the foil without deflection, small angles deflected some, and large angles deflected a few or even bounced back. He concluded that an atom consists of a tiny, dense, positively charged nucleus at the Centre, surrounded by a cloud of electrons at a large distance from the nucleus. He also calculated the size of the nucleus as about 10-15 m, which is much smaller than the size of the atom (about 10-10 m). This model could explain the stability and electrical neutrality of atoms, but it failed to explain the origin and nature of atomic spectra. ! Rutherford’s experiment) Bohr’s Model of Atom Bohr’s model of atoms was proposed by Niels Bohr in 1913, based on his study of hydrogen atomic spectra. He modified Rutherford’s model by introducing the concept of quantization of energy levels for electrons in an atom. He proposed that electrons revolve around the nucleus in fixed circular orbits, called shells or energy levels, with definite energies. He also proposed that electrons can jump from one orbit to another by absorbing or emitting a quantum of energy (photon) equal to the difference between their energies. He derived an expression for the radius and energy of an electron in an orbit as: r_n = n^2 h^2 / (4π^2 m k e^2) E_n = – m k e^4 / (2 h^2 n^2) where n is the principal quantum number (1, 2, 3,…), h is Planck’s constant (6.626 x 10-34 J s), m is the mass of electron (9.109 x 10-31 kg), k is Coulomb’s constant (8.987 x 109 N m^2 C^-2), e is the charge on electron (1.602 x 10-19 C). This model explained the origin and nature of hydrogen atomic spectra. Still, it failed to explain the spectra of other atoms, the fine structure of spectral lines, and the dual nature of matter and radiation. ! Bohr’s model) Quantum Mechanical Model of Atom The Quantum mechanical model of the atom is the most accepted and advanced model of the atom, based on the principles of quantum mechanics and wave mechanics. It was developed by various scientists, such as Louis de Broglie, Erwin Schrödinger, Werner Heisenberg, Max Born, and others, in the 1920s and 1930s. It considers an electron as a wave-particle duality, meaning it has both wave-like and particle-like properties. It describes an electron in terms of a wave function (ψ), which is a mathematical function that gives the probability of finding an electron in a given region of space. It also describes an electron in terms of four quantum numbers (n, l, m_l, m_s), which specify an atomic orbital’s size, shape, orientation, and spin. An atomic orbital is a three-dimensional region around the nucleus where the probability of finding an electron is maximum. The quantum mechanical model can explain the spectra of all atoms, the fine structure of spectral lines, and the dual nature of matter and radiation. !Quantum mechanical model) Dual Nature of Matter and Radiation The dual nature of matter and radiation is the concept that matter and radiation have wave-like and particle-like properties. It was proposed by Louis de Broglie in 1924, based on his hypothesis that if radiation can behave like particles (photons), then particles can also behave like waves. He derived an expression for the wavelength (λ) associated with a particle of mass (m) and velocity (v) as: λ = h / (m v) where h is Planck’s constant. This concept was experimentally verified by Davisson and Germer in 1927, who observed the diffraction pattern of electrons scattered by a crystal. This concept is also supported by Heisenberg’s uncertainty principle, which states that it is impossible to measure simultaneously both the position and momentum (or velocity) of a particle with absolute accuracy. The product of the uncertainties in position (Δx) and momentum (Δp) is always equal to or greater than h/4π. Δx Δp ≥ h/4π This implies that the more precisely we know the position of a particle, the less precisely we know its momentum, and vice versa. Photoelectric Effect The photoelectric effect is the emission of electrons from a metal surface when light of a suitable frequency falls on it. It was observed by Hertz in 1887 and explained by Einstein in 1905. It shows that light behaves like particles (photons) with energy proportional to their frequency (ν). The energy (E) of a photon is given by: E = h ν where h is Planck’s constant. The photoelectric effect can be explained by assuming that when a photon strikes a metal surface, it transfers its energy to an electron in the metal. Suppose the energy of the photon is greater than or equal to the minimum energy required to remove an electron from the metal (called work function, φ). In that case, the electron is ejected from the metal surface with some kinetic energy (K). The kinetic energy of the ejected electron is given by: K = h ν – φ This equation is called Einstein’s photoelectric equation. It shows that the kinetic energy of the ejected electron depends on the frequency of the incident light and not on its intensity. The intensity only affects the number of electrons ejected per unit time. The photoelectric effect has many applications, such as photovoltaic cells, photocells, photomultipliers, etc. !Photoelectric effect) Atomic Spectra Atomic spectra are the spectra of electromagnetic radiation emitted or absorbed by atoms when they undergo transitions between different energy levels. Atomic spectra can be classified into two types: continuous spectra and line spectra. Continuous spectra contain all wavelengths or frequencies within a given range, such as the spectrum of white light or black body radiation. Line spectra contain only certain discrete wavelengths or frequencies corresponding to specific transitions between energy levels, such as the spectrum of hydrogen or sodium atoms. Atomic spectra can identify elements, determine their atomic structure, measure their physical properties, etc. !Atomic spectra) De Broglie’s Hypothesis De Broglie’s hypothesis is that if radiation can behave like particles (photons), then particles can also behave like waves. It was proposed by Louis de Broglie in 1924 based on his analogy between light and matter. He derived an expression for the wavelength (λ) associated with a particle of mass (m) and velocity (v) as: λ = h / (m v) where m is the particle’s mass, v is the particle’s velocity, and h is Planck’s constant. This hypothesis was experimentally verified by Davisson and Germer in 1927, who observed the diffraction pattern of electrons scattered by a crystal. This hypothesis implies that matter has both wave-like and particle-like properties and that the wavelength of matter depends on its momentum. De Broglie’s hypothesis was a breakthrough in the development of quantum mechanics, as it provided a basis for the wave equation of Schrödinger, which describes the behaviour of electrons in atoms. De Broglie’s hypothesis also explains the origin of atomic spectra, as it suggests that electrons can only occupy those orbits in an atom with a circumference equal to an integral multiple of the wavelength of the electron. This means that only certain discrete energy levels are possible for electrons in an atom. They emit or absorb photons with specific frequencies when they jump from one level to another. De Broglie’s hypothesis also has many applications in various fields of science and technology, such as electron microscopy, electron diffraction, electron beam lithography, etc. Quantum numbers and orbitals: Quantum numbers specify the size, shape, orientation, and spin of an atomic orbital. An atomic orbital is a three-dimensional region around the nucleus where the probability of finding an electron is maximum. There are four quantum numbers: principal (n), angular (l), magnetic (m_l), and spin (m_s). The principal quantum number (n) determines the energy level and the distance of the orbital from the nucleus. It can have values from 1 to infinity. The angular quantum number (l) determines the shape or sublevel of the orbital. It can have values from 0 to n-1. The magnetic quantum number (m_l) determines the orientation or direction of the orbital in space. It can have values from -l to +l. The spin quantum number (m_s) determines the spin or direction of rotation of the electron in the orbital. It can have values of -1/2 or +1/2. The different shapes of orbitals are denoted by letters: s (spherical), p (dumbbell), d (double dumbbell), and f (complex). Aufbau principle, Pauli exclusion principle, and Hund’s rule: These rules govern the filling of electrons in orbitals in an atom. The Aufbau principle states that electrons are filled in orbitals in order of increasing energy, starting from the lowest energy orbital. The Pauli exclusion principle states that no two electrons in an atom can have the same set of four quantum numbers, which means that each orbital can hold a maximum of two electrons with opposite spins. Hund’s rule states that when there are more than one orbital of equal energy (degenerate orbitals), electrons are filled singly with parallel spins before pairing up. Electronic configurations of atoms: Electronic configurations are the arrangements of electrons in orbitals in an atom. They are written using the notation n lx, where n is the principal quantum number, l is the letter denoting the shape of the orbital, and x is the number of electrons in that orbital. For example, the electronic configuration of hydrogen (H) is 1s1, which means that it has one electron in the 1s orbital. The electronic configurations of atoms follow the Aufbau principle, Pauli exclusion principle, and Hund’s rule, as well as some exceptions due to stability and symmetry factors. This summary helps you to understand the structure of atoms better. If you have any questions or doubts, please feel free to ask me. I’m here to help. 😊 [...]Read more...
