Question
Write down the draw backs of the Bohr atom model.
Answer in Brief
Solution
The following are the drawbacks of Bohr atom model:
- The Bohr atom model is valid only for hydrogen atom or hydrogen-like-atoms but not for complex atoms.
- When the spectral lines are closely examined, individual lines of the hydrogen spectrum is accompanied by a number of faint lines. These are often called fine structures. This is not explained by Bohr atom model.
- Bohr atom model fails to explain the intensity variations in the spectral lines.
- The distribution of electrons in atoms is not completely explained by Bohr atom model.
