Assertion : Spin quantum number can have...

Assertion : Spin quantum number can have two values, `+(1)/(2) and -(1)/(2)`.
Reason : +and -signs signify the positive and negative wave functions.

A

If both (A) and (R) are correct and (R) is the correct explanation of(A).

B

If both (A) and (R) are correçt, but (R) is not the correct explanation of (A).

C

If (A) is correct, but (R) is incorrect.

D

If both (A) and (R) are incorrect.

Text Solution

Verified by Experts

The correct Answer is:
C
Plus and minus signs of spin quantum numbers imply that spin angular momentum of the electron, a vector quantity, acts in the same or opposite directions of orbital angular momentum.
