Erwin Schrdinger, in 1926, proposed an equation called Schrdinger equation to describe the electron distributions in space and the allowed energy levels in atoms. Bohr model of the hydrogen atom, therefore, not only ignores the dual behaviour of electron but also contradicts Heisenberg uncertainty principle.

This is not possible according to the Heisenbergs uncertainty principle which states that it is impossible to determine simultaneously, the exact position and exact momentum (or velocity) of an electron. Learn from your favourite Educator2. Photoelectric effect: The phenomenon of ejection of electrons from the surface of metal when light of suitable frequency strikes it is called photoelectric effect. In an atom many such orbitals are possible and electrons are filled in those orbitals in order of increasing energy in accordance with Pauli exclusion principle (no two electrons in an atom can have the same set of four quantum numbers) and Hunds rule of maximum multiplicity (pairing of electrons in the orbitals belonging to the same sub shell does not take place until each orbital belonging to that sub shell has got one electron each, i.e., is singly occupied). It includes all the topics given in NCERT class 11 Chemistry text book. The discovery of sub-atomic particles led to the proposal of various atomic models to explain the structure of atom.Thomson in 1898 proposed that an atom consists of uniform sphere of positive electricity with electrons embedded into it.

According to the quantum mechanical model of the atom, the electron distribution of an atom containing a number of electrons is divided into shells. PW offline classes in Kota at a very affordable fees structure. Rutherford model, which resembles the solar system, was no doubt an improvement over Thomson model but it could not account for the stability of the atom i.e., why the electron does not fall into the nucleus.
