Statement I: According to Bohr's model of hydrogen atom, the angular momentum of an electron in a given stationary state is not quantized.
Statement II : The concept of electron in Bohr's orbit, violates the Heisenberg uncertainty principle.

Statement I is correct but Statement II in incorrect.

Both Statement I and Statement II are incorrect.

Both Statement I and Statement II are correct.

Statement I is incorrect but Statement II is correct.

Text Solution

Verified by Experts

The correct answer is:

According to Bohr's model of hydrogen atom, angular momentum of an electron in given stationary states is quantised.
where,

Concept of electron in Bohr's orbit violates the Heisenberg's uncertainty principle because it considers electrons move in fixed orbitals and have known trajectories and position whereas according to Heisenberg's uncertainty principle it is not possible to measure position and momentum of electron simultaneously.
