Consider the following pairs of electrons

(A) (a) $n = 3, l = 1, {m}_{l} = 1, {m}_{s} = + \dfrac{1}{2}$
(b) $n = 3, l = 2, {m}_{l} = 1, {m}_{s} = + \dfrac{1}{2}$
(B) (a) $n = 3, l = 2, {m}_{l} = - 2, {m}_{s} = - \dfrac{1}{2}$
(b) $n = 3, l = 2, {m}_{l} = - 1, {m}_{s} = - \dfrac{1}{2}$
(C) (a) $n = 4, l = 2, {m}_{l} = 2, {m}_{s} = + \dfrac{1}{2}$
(b) $n = 3, l = 2, {m}_{l} = 2, {m}_{s} = + \dfrac{1}{2}$
