JEE PYQ: Atomic Structure Question 33
Question 33 - 2019 (10 Apr Shift 1)
The graph between $|\psi|^2$ and r (radial distance) is shown below. This represents:
(1). (3s orbital)
(2). (2s orbital)
(3). (1s orbital)
(4). (2p orbital)
Show Answer
Answer: (2)
Solution
The probability density curve shows one radial node, characteristic of 2s orbital ($n - \ell - 1 = 2 - 0 - 1 = 1$).
