Question

Bohr's theory cannot explain the following factor:
1) Stark effect
2)Zeeman effect
3)Both 1 and 2
4)None of these​

Answer 1

Answer:

3)both a and b

Explanation:

Bohr model could not explain those atoms which have more than one

electron like lithium, helium. This model was applicable only for those

atoms which have one electron.

Bohr theory explained only spherical orbits. There was no explanation for elliptical orbits.

This model failed to explain Zeeman Effect and stark effect.

Bohr model could not explain the uncertainty principle of Heisenberg.

Bohr model was not related with classification and periodicity of elements.

By using Bohr atomic model, one cant explain the intensity of spectrum line.

Hence option C is correct.
