Limitations of bohrs model.

Answer 1

___________________


$\sf{\underline{Limitations\:of\:Bohr's\:model.}}$


⚫The model is unable to explain to spectrum atoms of other than hydrogen.


⚫It is unable to explain the splitting of spectral lines in presence of magnetic field.


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

Answer 2

Limitations of Bohr's Model:-

⏩It is in violation of the Heisenberg Uncertainty Principle. The Bohr Model considers electrons to have both a known radius and orbit, which is impossible according to Heisenberg.

⏩The Bohr Model is very limited in terms of size. Poor spectral predictions are obtained when larger atoms are in question.

⏩It cannot predict the relative intensities of spectral lines.

⏩It does not explain the Zeeman Effect, when the spectral line is split into several components in the presence of a magnetic field.

⏩The Bohr Model does not account for the fact that accelerating electrons do not emit electromagnetic radiation.
