what is the main limitation of Bohr's model of atom

It violates the Heisenberg Uncertainty Principle. The Bohr atomic model theory considers electrons to have both a known radius and orbit i.e. known position and momentum at the same time, which is impossible according to Heisenberg.The Bohr atomic model theory made correct predictions for smaller sized atoms like hydrogen, but poor spectral predictions are obtained when larger atoms are considered.It failed to explain the Zeeman effect when the spectral line is split into several components in the presence of a magnetic field.It failed to explain the Stark effect when the spectral line gets split up into fine lines in the presence of electric field.

Hey there!
Answer:
Limitations are ;
1) It explain the spectra of only hydrogen like structure i.e only one electron. It fails to explain the spectra of multi - electrons atoms.
2) It does not tell about the relative intensities of spectral lines.
3) It considers an electron only as a particle, but electrons exhibit wave nature also.
4) It defined both position and more momentum with complete certainty but this is against the Heisenberg uncertainty principle.
5) The research shows that the charge distribution due. to electrons in different orbits is altogether different from the one assumed n Bohr's model of atom.
