Which of the following is not possible for 4p or 3d electrons?

A

`n = 3, l = 2, m = +1, s = +(1)/(2)`

B

`n = 4, l = 1, m = 0, s = +(1)/(2)`

C

`n = 3, l = 3, m = +3, s = +(1)/(2)`

D

`n = 4, l = 2, m = -1, s = +(1)/(2)`

Text Solution

Verified by Experts

The correct Answer is:
C
For 4p orbital, n = 4 and l =2
For 3d orbital, n = 3 and l = 2
So option (C ) does not show 4p or 3d. It indicates 3f-orbital which is not possible.
