Main postulates of bohr's atomic model in simple points

Answer 1

The main postulates of Bohr's atomic model are-

1) An electron can revolve around the nucleus in certain fixed orbits of definite energy without emission of any radiant energy. Such orbits are called stationary orbits.

2) An electron can make a transition from a stationary state of higher energy E2 to a state of lower energy E1 and in doing so, it emits a single photon of frequency, ν=E2−E1h where h is the Planck's constant.Conversely, on absorbing an energy, E2−E1 when the electron is at energy E1, the electron can make a transition from E1 to E2.

3) Only those orbits are allowed for which the angular momentum of the electron is an integral multiple of h2π.Thus, L=nh2π where n=0,1,2,.....
