Question

weakness of bohrs model of atom

Answer 1

1) the path of electron around nucleus is considered to be circular of definite radius but in reality it can be at any distance from the nucleus. 2) the model is based on spectra of atoms and newton's laws of motion which are not applicable to microscopic particles.

Answer 2

1.bohr’s atomic model does not explain multi electron system elements

2.it does not explain the effect of magnetic and electric field on atomic spectra. it does not explain stark and zeeman effect.

3.it does not follow Heisenberg Uncertainty Principle. according to bohr’s atomic model, momentum and position are very defined. but both do not simultaneously determined.

4.bohr’s atomic model was two dimensional but its three dimensional

5.orbit was circular in bohr’s atomic model but modern research shows that its three dimensional
