Question

Match the following

(A) Number of subshell in a shell	(P) $2 (2 l + 1)$
Column - I	Column - II
(B) Number of orbital in a shell	(Q) $n$
(C) Number of $e^{-}$ in a shell	(R) $2 n^{2}$
(D) Number of $e^{-}$ in a subshell	(S) $n^{2}$
	(T) $(4 l + 2)$

TestHub · Accepted Answer

(A) Number of subshells in a shell depends on the principal quantum number $n$ .

Rule: Number of subshells = $n$ → Q

(B) Number of orbitals in a shell depends on the sum over subshells $l = 0$ to $n - 1$ .

Formula: Number of orbitals in a shell = $n^{2}$ → S

(C) Number of electrons in a shell: Maximum electrons = $2 n^{2}$ → R

(D) Number of electrons in a subshell depends on $l$ : $2 (2 l + 1)$ → P, T
