Limitation of Bohr's model of atom

• It could not explain the line spectrum of multi electron atoms.

• This model failed to explain the effect of magnetic field on the spectra of atoms (Zeeman effect).

• The effect of electric field on the spectra could not be explained by Bohr's model (Stark effect).

• The shapes of molecules arising out of directional bonding could not be explained.

• The dual nature of electrons (both as wave and particle) and the path of motion of the electron in well defined orbits were not correct.
