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

Question

Quizplus · Accepted Answer

The magnetic quantum number ($m_l$) can have values from $-l$ to $+l$, including zero. For $l = 3$, the allowed values of $m_l$ are -3, -2, -1, 0, 1, 2, and 3. Therefore, 4 is not an allowed value.
