Atomic Structure - NEET Physics Questions

Question 31: easy

Assertion (A): In solid each electron will have a different energy level.

Reason (R): In solid crystal each electron has a unique position and no two electrons see exactly the same pattern of surrounding charges.

1. Both (A) & (R) are true and the (R) is the correct explanation of the (A)

2. Both (A) & (R) are true but the (R) is not the correct explanation of the (A)

3. (A) is true but (R) is false

4. Both (A) and (R) are false

View Answer

Due to the Pauli exclusion principle, no two electrons can occupy the same quantum state. In a solid, each electron experiences a unique electrostatic environment. Thus, Assertion (A) is true, and Reason (R) provides the correct explanation for it.
