Which ONE is not an allowed set of quantum numbers? (a. 3s b. 2d c. 1s d. 4p)?

2d, there is no 2d orbital

Which ONE is not an allowed set of quantum numbers? (a. 3s b. 2d c. 1s d. 4p)?
2d is impossible, because the d orbital is restricted to energy levels 3 and greater...
Reply:1 can only have s suborbitals, 2 can only have s and p, 3 can only have s,p, and d. 4 can have s,p,d and f. The answer is 2d cannot exist.
