Question

drawbacks of Bohr's model theory
​

Answer 1

Answer:

DRAWBACKS OF BOHR’S MODEL:

1. It was primarily for hydrogen atom
2. It couldn’t elaborate spectra of multi-electron atoms
3. Wave nature of electron was not justified by the model (inconsistent with the de Broglie’s hypothesis of dual nature of matter)
4. It didn’t illustrated molecules making process of chemical reactions
5. It violated Heisenberg’s Principal(Δx× Δp ≥nh/(2π)) which said that it was impossible to evaluate theprecise position and momentum of electron (and other microscopic particles) simultaneously.Only their probability could be estimated.
6. Zeeman effect(spectral lines variation due to external magnetic field) and Stark Effect(spectral lines variation due to external electric field) couldn’t be described by the model
