Question

Assertion :The angular momentum of the electron revolving in a stationary orbit is equal to integral multiples of $h/2\pi$. Reason: Angular momentum of an electron orbiting around the nucleus is quantized.

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.
• C. Assertion is correct but Reason is incorrect.
• D. Assertion is incorrect but Reason is correct.

Answer 1

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.

According to Bohr's atomic model an electron can revolve around the nucleus only in discrete orbits known as stationary orbits for which angular momentum of electron is integral multiple of $h/2\pi$, this principal is known as quantization of Angular momentum.
