If the principal quantum number is seven (n = 7) and the angular momentum quantum number is three ( = 3), which of the following values is not an allowed value of the magnetic quantum number (m_l)?

Question

Quizplus · Accepted Answer

The allowed values of m for a given l value range from -l to +l, so for l=3, the allowed values of m are -3, -2, -1, 0, +1, +2, and +3. Therefore, the value of m = 4 is not an allowed value.
