Main postulates of Bohr's atomic theory are: 1. Electrons revolve around the nucleus in circular path, which are known as "ORBITS" or "ENERGY LEVEL". 2. Energy of an electron in one of its allowed orbits is fixed.As long as an electron remains in one of its allowed orbit, it can not absorb or radiate energy.
