Match the following — Atomic Structure Chemistry Question

💡 Solution & Explanation

Number of radial nodes = $n - l - 1$, and angular nodes = $l$. For (A) 2s: $n=2, l=0$, radial = 1, angular = 0 (Matches R, S). For (B) 1s: $n=1, l=0$, radial = 0, angular = 0 (Matches Q, S). For (C) 2p: $n=2, l=1$, radial = 0, angular = 1 (Matches P, Q). For (D) 3p: $n=3, l=1$, radial = 1, angular = 1 (Matches P, R). Therefore, correct answer is A-R,S; B-Q,S; C-P,Q; D-P,R.
