MCQ
Given below are two statements:

Statement $I:$ According to Bohr's model of hydrogen atom, the angular momentum of an electron in a given stationary state is quantised.

Statement $II:$ The concept of electron in Bohr's orbit, violates the Heisenberg uncertainty principle.

In the light of the above statements, choose the most appropriate answer from the options given below:

  • Both Statement $I$ and Statement $II$ are correct.
  • B
    Statement $I$ is correct but Statement $II$ is incorrect.
  • C
    Statement $I$ is incorrect but Statement $II$ is correct
  • D
    Both Statement $I$ and Statement $II$ are incorrect.

Answer

Correct option: A.
Both Statement $I$ and Statement $II$ are correct.
a
According to Bohr's model the angular momentum is quantised and equal to $\frac{ nh }{2 \pi}$.

Heisenberg uncertainty principle explains orbital concept, which is based on probability of finding electron.
