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. read more
there are few drawbacks: bohr’s atomic model does not explain multi electron system elements; it does not explain the effect of magnetic and electric field on atomic spectra. it does not explain stark and zeeman effect. read more
Niels bohr atomic theory and Drawback of Bohr's theory.The theory could not account for the spectra of atoms more complex than hydrogen. The theory does not give any information regarding the distribution and arrangement of electrons in an atom. read more
