Atomic Structure

According to Bohr's quantization rule, the angular momentum of an electron in a hydrogen atom is quantized. This means the electron can only occupy certain allowed energy levels.
Bohr's postulate:
So, the angular momentum is not just any value — it is a whole number multiple of , not of .
Why not the other options?
- (A) Quantized as multiples of : incorrect — should be .
- (B) Continuous: Bohr’s theory explicitly proposed quantization.
- (D) Equal to zero: This is not true; lowest level still has non-zero angular momentum.
