Question

Consider the following pairs of electrons

(A) (a) n = 3, = 1, m1 = 1, ms = +

      (b) n = 3, 1 = 2, m1 = 1, ms = +

(B) (a) n = 3, = 2, m1 = 2, ms =

      (b) n = 3, = 2, m1 = 1, ms =

(C) (a) n = 4, = 2, m1 = 2, ms = +

      (b) n = 3, = 2, m1 = 2, ms = +

The pairs of electrons present in degenerate orbitals is/are :

Choose an option

Show full solutionCorrect option: B
Correct answer
BOnly (B)

Step-by-step explanation

For degenerate orbitals, only the value of m must be different. The value of (n + l) must be the same.

Hence, the pair of electrons with quantum numbers given in (B) are degenerate.
