WebPostulates of Bohr's atomic model: Bohr proposed that in an atom electron is revolving around the nucleus in a definite circular path called orbits or shells. These orbits are called ‘stationary orbits’ and each orbit or shell possesses fixed energy. The energy levels are represented by an integer called quantum numbers where n = 1, 2, 3,..... The Bohr model of the atom was proposed by Neil Bohr in 1915. It came into existence with the modification of Rutherford’s model of an atom.
