JEE PYQ: Atomic Structure Question 7
Question 7 - 2021 (18 Mar Shift 1)
A certain orbital has no angular nodes and two radial nodes. The orbital is:
(1). (2s)
(2). (3s)
(3). (3p)
(4). (2p)
Show Answer
Answer: (2)
Solution
No angular nodes $\Rightarrow \ell = 0$ (s orbital). Radial nodes $= n - 0 - 1 = 2 \Rightarrow n = 3$. Orbital is 3s.
