Question

Limitations of Bohr's atomic model.

Answer 1

Hey there!

Answer:


Following are the limitations of Bohr's atomic model:

1). It explains the spectra of only hydrogen like atom i.e atoms having only one electrons such as H, $He^{+}$ etc. It fails to explain the spectra of multi electron atoms.


2). When a spectral lines is observed under a powerful microscope, it is found that to consist of number of closely spaced lines. Bohr's atomic model does not explain the fine structure of a spectral
lines.


3). It does not explain the splitting of a spectral lines into a number of spectral lines under the effect of magnetic field and electric field.


4). It does not explain the relative intensity of spectral lines.


5). Bohr's atomic model explain the both momentum and position with certainty. Which is against the Heisenberg uncertainty principle.


6). It considers an electron only as a particle, but electrons possess wave nature also.
