Question

defects of Bohrs atomic model any 3

Answer 1

Answer:

Explanation:

1. Bohr treated electrons as particles where according to de Broglie's hypothesis, having a very low mass, electron also exhibits wave nature.

2. Bohr's model was adequate only for nucleus having only one electron e.g. Hydrogen, He+1, Li+2 etc. Bohr's model could not explain the spectra of multi-electronic atoms.

3. Bohr's model was two-dimensional where an atom is three-dimensional.

4. Using a better spectrometer, the spectra showed very fine lines. Bohr's model could not explain the origin of those fine lines.

5. Bohr's model could not explain the effect electric field and magnetic field on spectra.
