B)-2
C)0
D)3

Question

Quizplus · Accepted Answer

The allowed magnetic quantum number, m, ranges from -l to +l, where l is the orbital angular momentum quantum number, and in this case l=5. Therefore, the possible values of m are -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, and 5. Choice A, 6, is not part of this range, and therefore is not an allowed orbital magnetic quantum number for hydrogen.
