JEE Advanced levelSingle correct optionDifficulty 3 of 3as155

An orbital has a total of 4 nodes (radial plus angular) and its electron has orbital angular momentum $6 ℏ$ . The number of radial nodes is

A3
B1
C4
D2

Answer: D

L = 6 ℏ

means

l = 2

(2 angular nodes). Radial

= 4 - 2 = 2

(this is a 5d orbital,

n - l - 1 = 2

).
