If the principal quantum number is seven (n = 7) and the angular momentum quantum number is three ( $\ell$ = 3), which of the following values is not an allowed value of the magnetic quantum number (m_l)? A) 0 B) 1 C) 2 D) -3 E) 4

Question

Quizplus · Accepted Answer

The magnetic quantum number $m_l$ can take on integer values from $-\ell$ to $+\ell$. For $\ell = 3$, $m_l$ can be -3, -2, -1, 0, 1, 2, or 3. Therefore, 4 is not an allowed value.
