Question

what are the limitations and postulates of Neil's Bhor

Answer 1

The postulates of Bohr model are the following:
1.He could explain the stability of an atom.
2.Bohr's model could explain hydrogen atom.
3.Bohr's model account the existence of so many lines hydrogen spectrum.
4.Bohr's model helped in calculating the radius of a particular orbit.

The limitations of Bohr model are the following:
1.He could not explain spectrum of atoms having more than one electron.
2.It could not explain the shape of the molecule.
3.It was unable to explain Zeeman effect and Stark effect.
4.It is against de-Broglie's relation and Heisenburg's unceryainity principle.
Hope you got it

Answer 2

Limitations of Bohr Atomic Model Theory

It violates the Heisenberg Uncertainty Principle. ...The Bohr atomic model theory made correct predictions for smaller sized atoms like hydrogen, but poor spectral predictions are obtained when larger atoms are considered.
