In 1913 Prof. Niels Bohr proposed a quantum model of the atom in order to explain the stability of the atom. Assumptions made by Bohr to explain his atomic model. 1. Bohr's First Assumption: Electrons rotate in the non-radiating circular orbit around the nucleus in the stationary orbit. The centripetal force keeps all the electrons in the circular orbit which is maintained by the Coulomb force. i.e. Centripetal force is equal to Coulomb force. Let's say an electron (-e) of mass m is moving with a velocity v and in rad…
