Question

what is the demarits of bhor's theory?

Answer 1

heya @user
here is your answer

______________________________

demarits of bhor's theory are following ::-

★ it is restricted to one electron system only

★ it did not give any idea about screening effect.

★ it is based on Planck's Quantum theory which signifies the dual nature of electron inspire of that an electron has been treated as an particle.

★ he could not explain the quantisation of angular momentum.

★ it contradicts Heisenberg's unceetainly particle

Answer 2

heyy there!
here is your answer...

THE DEMARITS OF BHOR'S THEORY ARE..

1) He could not explan the quantisation of angular momentum.

2) De Broglie suggested that electrons like light have dual character. It has particle and wave character. Bohr treated the electron only as particle.

3) Another objection to Bohr’s theory came from Heisenberg’s Uncertainty Principle.

According to this principle ” It is impossible to determine simultaneously the exact position and momentum of a small moving particle like an electron “.

4) It does not explain the spectra of atoms having more than one electron.

5) Bohr’s atomic model failed to account for the effect of magnetic field (Zeeman effect) or electric field (Stark effect) on the spectra of atoms or ions.

hope this helps u..
