Question

State the basic postulates of Bohrs theory of atomic spectra.

Answer 1

The basic postulates of Bohr’s theory of atomic spectrum are:

1. The electrons revolve around the nucleus in a certain selected circular path is called an orbit.
2. The spectrum of light emitted from an electron is called the line spectrum.
3. If electrons jump from a lower energy level to a higher energy level, it absorbs the energy.
4. If electrons jump from a higher energy level to a lower energy level, it losses the energy.
5. Each shell or an orbital has fixed energy, and the circular orbitals are known as the orbital shells
