Match List-I with List-II:

List-I (Quantum number) (a) $n = 2, l = 1$ (b) $n = 3, l = 2$ (c) $n = 3, l = 0$ (d) $n = 2, l = 0$

List-II (Orbital) (i) 2s (ii) 3s (iii) 2p (iv) 3d

Choose the correct answer from the options given below:

(a)-(iii), (b)-(iv), (c)-(i), (d)-(ii)

(a)-(iv), (b)-(iii), (c)-(i), (d)-(ii)

(a)-(iv), (b)-(iii), (c)-(ii), (d)-(i)

(a)-(iii), (b)-(iv), (c)-(ii), (d)-(i)

Step-by-Step Solution

The subshell notation is derived from the principal quantum number ( $n$ ) and the azimuthal quantum number ( $l$ ). The value of $l$ corresponds to specific subshells: $l=0 \rightarrow s$ , $l=1 \rightarrow p$ , $l=2 \rightarrow d$ , $l=3 \rightarrow f$ , .

For (a) $n = 2, l = 1$ : The shell is 2 and the subshell is p ( $l=1$ ). Representation: 2p. Matches (iii).
For (b) $n = 3, l = 2$ : The shell is 3 and the subshell is d ( $l=2$ ). Representation: 3d. Matches (iv).
For (c) $n = 3, l = 0$ : The shell is 3 and the subshell is s ( $l=0$ ). Representation: 3s. Matches (ii).
For (d) $n = 2, l = 0$ : The shell is 2 and the subshell is s ( $l=0$ ). Representation: 2s. Matches (i).

Correct matching sequence: (a)-(iii), (b)-(iv), (c)-(ii), (d)-(i).
