Give drawbacks of bohr's model of an atom.

Explanation

The main limitations of the Bohr.s model of atom are as follows:
(i) It could not explain the spectra and energy of atoms containing more than one electron.
(ii) Bohr.s model could not explain the reason, why atoms combine to form molecules by chemical bonds and why the molecules are more stable than their constituent atoms.. l
(il) No justification was given for the basis of quantisation of the momentum of electron.
(iv) Bohr.s theory could not explain the origin of the observed fine structure of spectral lines in any atomic spectra.
