Question

Assertion: Angular momentum of an electron in any orbit is given by angular momentum $=\frac{n.h}{2\pi }$, where n is the principal quantum number.
Reason: The principal quantum number, n, can have any integral value.

• A. If both assertion and reason are true and the reason is a correct explanation of the assertion.
• B. If both assertion and reason are true but reason is not a correct explanation of the assertion
• C. If the assertion is true but reason is false
• D. If both the assertion and reason are false
• E. If the assertion is false but the reason is true

Answer 1

The correct option is B If both assertion and reason are true but reason is not a correct explanation of the assertion

The Quantization of electron refers to the absorption or emission of energy in discrete packets or quanta.As the intensity of electromagnetic energy decreases or increases,it steps up or down from one quantized level to other quantized level,rather than follow a smooth or continuous curve.
