Quizplus · Accepted Answer

The magnetic quantum number (denoted as $m_l$) can take on any integer value from $-\ell$ to $+\ell$, where $\ell$ is the azimuthal quantum number or orbital angular momentum quantum number. This range includes zero and describes the orientation of the orbital in space relative to the other orbitals.
