Consider the following pairs of electrons

(A) (a) n = 3, $l$ = 1, m₁ = 1, m_s = + ${1 \over 2}$

(b) n = 3, 1 = 2, m₁ = 1, m_s = + ${1 \over 2}$

(B) (a) n = 3, $l$ = 2, m₁ = $-$ 2, m_s = $-$ ${1 \over 2}$

(b) n = 3, $l$ = 2, m₁ = $-$ 1, m_s = $-$ ${1 \over 2}$

(C) (a) n = 4, $l$ = 2, m₁ = 2, m_s = + ${1 \over 2}$

(b) n = 3, $l$ = 2, m₁ = 2, m_s = + ${1 \over 2}$

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

Accepted Answer

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.
