Which one of the following represents an acceptable possible set of quantum numbers (in the order n, l, m_l, m_s)for an electron in an atom? A)2, 1, -1, 1/2 B)2, 1, 0, 0 C)2, 2, 0, 1/2 D)2, 0, 1, -1/2 E)2, 0, 2, +1/2

Question

Quizplus · Accepted Answer

The set of quantum numbers (2, 1, -1, 1/2) is valid because: n=2 (principal quantum number), l=1 (angular momentum quantum number, can be 0 to n-1), m_l = -1 (magnetic quantum number, can be -l to +l), and m_s = 1/2 (spin quantum number, can be +1/2 or -1/2).
