Question

mention two limitations of Bohr's theory

Answer 1

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.

Answer 2

1)Bohr was not able to explain electron orbits of large atom/ many electrons
2) Electron could not circle around nucleus like a planet.
