Answer 2

The correct question is -

Which is not the permissible subshell

(A) 2d

(B) 4f

(C) 6p

(D) 3s

Answer:

A is the proper response. as in the second shell, there are two subshells, $2s$ and $2p.$

Explanation:

Subshells of four different sorts are classified as s, p, d, and f in a sequence of increasing energy within the shells. The very first shell has just an s subshell; the second contains both an s and p subshell; the third contains s, p, and d subshells; and the fourth contains s, p, d, and f subshells.

The number of subshells that make up the shell is determined by the n (shell) number.

(3f subshell  is not permissible reason is mentioned above)
