Question

what are the drawbacks of bohrs atomic model

Answer 1

there are few drawbacks:bohr’s atomic model does not explain multi electron system elementsit does not explain the effect of magnetic and electric field on atomic spectra. it does not explain stark and zeeman effect.it does not follow Heisenberg Uncertainty Principle. according to bohr’s atomic model, momentum and position are very defined. but both do not simultaneously determined.bohr’s atomic model was two dimensional but its three dimensionalorbit was circular in bohr’s atomic model but modern research shows that its three dimensional

Answer 2

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 was two-dimensional where anatom is three-dimensional.
