1p and 3f are not possible.

Explanation: Principle Quantum Numbers : It describes the size of the orbital and the energy level.

For 1 p: n=1 and l can have value 0 to (n-1) i.e. 0 only.

For 2s : n=2 and l can have value 0 to (n-1) i.e. 0 and 1 only.

For 2p :

For 3f:

For 3d :

For 4f :

For 4d :
