yes
Yes. In Ix class you have few drawbacks. Always it's better to learn beyond your text book.
can it come in or exam ?
no in exam point, it will be not be asked. Be relaxed
ok
As an extra information, you ha've to learn
yes
This question was found in a Class 9 SA2 Sample paper. So, asked ☺
ohk
thanks for asking it

The bohrs model could not explain the formation of spectrum other than hydrogen.
It could not explain the the stark and zeeman effect.
He considered electrons as particles but according to de-broglie concept electrons were not particles.
It could not account for the spectrum lines.
It cannot predict the relative intensities of spectral lines.

Limitations of Bohr' s Model:
1. Bohr's theory fails to explain the spectra of multielectron atoms.
2.It could not explain the fine structure of atomic spectrum obtained by a spectroscope of high resolving power.
3. It does not explain the splitting of spectral lines into a group of finer lines under the influence of magnetic field ( Zeeman effect) and electric field ( Stark effect).
4. Bohr' s theory predicts definite orbits for revolving electrons. It is against the wave nature of electrons.
5. Bohr' s theory is not in agreement with Heisenberg 's uncertainty principle.

what was Heisenberg's principle
uncertainty principle states that " it's impossible to determine simultaneously the exact position and exact momentum or velocity of sub atomic particle like electron in an atom"
is that possible?
It states it's impossible to determine
oh sry
and thank u
welcome
