Q.
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: [2023]

1 Both Statement I and Statement II are correct

2 Statement I is correct but Statement II is incorrect

3 Statement I is incorrect but Statement II is correct

4 Both Statement I and Statement II are incorrect

Ans.
(1)

According to Bohr's model, orbital angular momentum of stationary orbit is quantized, which is equal to $\frac{n h}{2 π} (n = No. of orbit) .$ Heisenberg's uncertainty principle explains the orbital concept, which depends on the probability of finding an electron.

Solution

1 Both Statement I and Statement II are correct

2 Statement I is correct but Statement II is incorrect

3 Statement I is incorrect but Statement II is correct

4 Both Statement I and Statement II are incorrect

Ans.
