Chemistry, grade 12 - Quantum numbers

Question

Among the combinations of quantum numbers, which do not work?



A) n = 2; l = 1; m_l = 1, s = = + 1/2

B) n = 3; l = 2; m_l = - 2, s = = - 1/2

C) n = 1; l = 0; m_l = 1, s = = + ½

D) n = 3; l = 2; m_l = 0, s = = - 1/2

Answer 1

C) n = 1; l = 0; m_l = 1, s = + ½

The reason this combination does not work is because when l = 0, m_l can only be 0, and not 1.
