Question

Write 5 limitations of BOHR model of atom .......

Answer 1

The limitations of BOHR model of atom :

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.

Answer 2

Explanation:

LIMITATIONS

OF

BOHR'S

MODEL

OF

ATOM---------

1》 it does not explain spectrum of multi- electron atom.

2》 it does not explain why angular momentum related with

nh/2pie .

3》 it does not explain the effect of electric field(stark effect) or magnetic field(Zeeman effect) on hydrogen spectrum

4》》 it does not explain about dual nature of matter which was explained by the

de-brogelie.

5》》 it does not explain uncertainty in position and velocity of electrons which can be explained by Heisenberg principle.
