Question

what are the limitation of of Bohr's atomic model ?

Answer 1

he could not explain stark and Zeeman effects, he could not say reason why energy is quantised,he could not explain spectra of other atoms with more than one electron

Answer 2

$\Huge \bf{\red{Answer}}$

❃ The limitations of Bohr's atomic model are ;

☘ It fails to account for the finer details (doublet,that is two closely spaced line)of the hydrogen atom spectrum observed by using sophisticated spectroscopic techniques .

☘ This model is also unable to explain the spectrum of atoms other than hydrogen, for example, Helium atom which possesses only two electrons .

☘ Further Bohr's theory was also unable to explain the splitting of spectral lines in the presence of magnetic field (Zeeman Effect) or an electric field (stark effect ).

☘ It could not explain the ability of atoms to form molecules by chemical bonds .
