Differentiate between Shell,Sub-shell and Orbital Video Lecture

Differentiate between Shell, Sub-shell and Orbital Video Lecture Shell Shell is the path taken by electrons around the nucleus of an atom. Subshell The subshell is the path an electron follows within a shell. Orbital The orbital function depicts the wavelike behaviour of an electron. Conclusion Atoms are made up of electrons, protons, and neutrons. …

What is the difference between ionic and covalent bond?

What is the main difference between ionic and covalent bond? ANSWER : Ionic Bond : The bond formed by the complete transfer of electrons from one atom to another is called an ionic bond. Its also known as Electrovalent Bond. FORMATION OF IONIC BOND:  Following are the conditions that are necessary for the formation of …

Gas Discharge Tube Experiment | Discovery of Cathode rays

Discharge tube Experiment (William Crooks Experiment) (Discovery of Electrons / Cathode rays)  Gases are bad conductors of electricity but it is observed that at low pressure they conduct electricity. For this William purpose Crooks developed a discharge tube or cathode ray tube. The gas discharge tube consists of : 1. Cylindrical glass tube 2. Two …

Planck’s Quantum Theory of Radiation| Black body radiation

Planck’s Quantum Theory of Radiation: In 1900, a German Physicist Max Planck had studied radiations emitted by hot black bodies and presented the results of his famous black body radiations experiments, which showed that light has a dual character, behaving like a particle as well as a wave. He gave the quantum theory of radiation …

What is Charles Law in Simple Words ?

Charle’s Law in Simple Words Jacques Charles, in 1662, gave the law known as Charle’s law. It relates the volume and absolute temperature of ideal gases at constant pressure and mass. Charle’s Law Statement According to Charle’s law “For a fixed mass of a gas, the volume is directly proportional to absolute temperature at constant …

What are the Defects of Bohr’s Atomic Model?

What are the Defects of Bohr’s Atomic Model? In 1913 Neil Bohr’s presented a new model for an atom, known as Bohr’s atomic model. Niels Bohr model describes an atom as a small positively charged nucleus surrounded by electrons that travel in circular orbits around the positively charged nucleus like planets around the sun in …

Bohr Model of Atom | Main Postulates | Bohr Model

Bohr Model: (Bohr’s atomic model for hydrogen atom) Neils Bohr’s, 1913 proposed a model of an atom based on the planks quantum theory of radiation. Main Postulates of Bohr’s theory: The basic postulates of Bohr’s theory are: An atom consists of small, heavily positively charged nucleus around which electrons revolve in definite circular paths called …

Rutherford’s Atomic Model (Gold Foil Experiment) – Chemistry Notes

Rutherford’s Atomic Model Rutherford,1911 performed an experiment in order to find the arrangement of electrons and protons in an atom. Rutherford’s Gold Foil Experiment Rutherford bombarded a very thin gold foil about 0.00004 cm thickness with alpha particles. Alpha particles were obtained from the disintegration of polonium. Alpha particles are helium nuclei. i.e. He ++ …
