NEET Physics (general) Assertion Reason Question

Type: Assertion Reason-assertion-Easy-Class 12

Assertion (A): In semiconductors, the valence band is completely occupied at absolute zero. | Reason (R): The valence band and conduction band in semiconductors are separated by a small energy gap at absolute zero.

A

Both A and R are true and R is the correct explanation of A.

B

Both A and R are true but R is not the correct explanation of A.

C

A is true but R is false.

D

A is false.

Correct Answer

Option A

Detailed Explanation

In semiconductors, the valence band is fully occupied by electrons at absolute zero, and the conduction band is empty. The separation by a small energy gap supports this configuration.
