Limitations of Bohr’s model of atom:

• It failed to account for the finer details of the hydrogen spectrum. For instance splitting of a line in the spectrum into two closely spaced lines.
• It was also unable to explain spectrum of atoms containing more than one electron.
• It was unable to explain Zeeman effect, i.e. splitting of spectral line in the presence of magnetic effect.
• It also failed to explain Stark effect, i.e. splitting of spectral line in the presence of an electric field.
• It could not explain the ability of atoms to form molecules by chemical bonds.
