What are the postulates of Bohr's atomic model?
The Bohr's postulates -
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
Conversely, on absorbing an energy,
3) Only those orbits are allowed for which the angular momentum of the electron is an integral multiple of
