Question

State bohr's postulates for an atom calculate energy of moving electron for nth

Answer 1

E=nhc'/lamda
postulates of Bohr's atom
1)electron in an atom could revolve in certain orbits without the emission of radiant energy,.
2)electrons revolve around the nucleus only in those orbits for which the angular momentum is some integral multiple of h/2π
.3)an electron might make a transition from one of its specified non-radiating orbits to another of lower energy
