Drawbacks of Bohr’s atomic model are;
It ignores the finer features of the hydrogen atom spectrum obtained using sophisticated spectroscopic techniques.
It cannot account for the spectrum of atoms other than hydrogen, such as the helium atom, which has only two electrons.
It is also unable to explain the splitting of spectral lines in the presence of a magnetic or electric field (Zeeman effect) (Stark effect).
It could not account for atoms’ ability to create molecules through chemical bonding.
Final Answer:
Hence, The Drawback of Bohr’s atomic model is It ignores the finer features of the hydrogen atom spectrum obtained using sophisticated spectroscopic techniques.
