JEE PYQ: Atomic Structure Question 23

Question 23 - 2020 (05 Sep Shift 2)

The correct statement about probability density (except at infinite distance from nucleus) is:

(1). (It can be zero for 1s orbital)

(2). (It can be negative for 2p orbital)

(3). (It can be zero for 3p orbital)

(4). (It can never be zero for 2s orbital)

Show Answer

Answer: (3)

Solution

3p has 1 radial node ($n - \ell - 1 = 3 - 1 - 1 = 1$), so $\psi^2$ can be zero.
