State any two limitations of Bohr's atomic model.

Text Solution

AI Generated Solution

**Step-by-Step Solution:** 1. **Introduction to Bohr's Model**: - Bohr's atomic model was proposed by Niels Bohr in 1913 to explain the behavior of electrons in atoms, particularly hydrogen. 2. **Limitation 1 - Hydrogen Spectrum**: - One of the limitations of Bohr's model is that it cannot explain the relative intensities of the spectral lines in the hydrogen spectrum. While it predicts the wavelengths of the spectral lines, it does not account for the intensity variations of these lines. ...
