Question

which of the following orbital are not possible ??..1p 3f 2p 3d 4f​

Answer 1

Answer:

2p

Explanation:

The first shell has only one sub-shell, i.e., 1s, which has only one orbital, i.e., 1s orbital. Therefore, 1p orbital is not possible. (ii) The second sub-shell has two subshells, i.e., 2s and 2p. Therefore, 2s orbitals are possible.
