Bohr’s Atomic, Theory, An electron is a tiny,, negatively charged, PARTICLE that, revolves round the, atomic nucleus., , PARTICLE, 1. A particle occupies a well-defined position in space i.e. a, particle is localized in space e.g. a grain of sand, a cricket ball, etc., 2. When a particular space is occupied by one particle, the, same space cannot be occupied simultaneously by any other, particle. In other words, particles do not interfere., 3. When several particles are present in a given region of space,, their total value is equal to their sum i.e it is neither less nor, more.

Matter behaves as wave and is associated with a, wavelength. Wavelength of the Matter Wave or de, Broglie wave is expressed mathematically by the, , de Broglie’s Equation

NEED FOR A NEW APPROACH TO ATOMIC STRUCTURE, Quantum mechanics is the branch of, science, that, deals, with, the, mathematical description of the motion, and interaction of subatomic particles, based on the concept of :, Quantization of energy: Energy released or, absorbed in discrete values or packets called quanta, , E = hν, , Wave-particle, duality, electromagnetic radiation, , Explains:, • Quantum theory is the theoretical basis of, modern, , physics, , –, , Quantum, , Physics,, , Quantum Chemistry, quantum field theory,, quantum technology, etc., • The nature and behavior of matter and, energy at the atomic and subatomic level., , of, , matter, , and, , The uncertainty principle – The probabilistic, interpretation of behaviour of subatomic particles, , • How the particles at the subatomic level, work – helps in unlocking the mysteries of, how, , the, , Universe, , composition., , functions, , and, , its

QUANTUM, MECHANICAL MODEL, OF AN ATOM, (Currently Accepted Model), Cloud-like, appearance, of, Electronic motion due to their, wave nature. Nucleus is made of, Protons & neutrons which are, further made up of quarks. Each, proton is composed of two upquarks and a down quark while, each neutron is composed of two, down-quarks and an up-quark., Quarks are held together by, gluons., Link to Read more:, https://en.wikipedia.org/wiki/Stand, ard_Model
