What are the possible allowed values of the orbital magnetic quantum number m_ℓ of the electron?

Question

Quizplus · Accepted Answer

The orbital magnetic quantum number, denoted as $m_l$, can take on values from $-l$ to $+l$ in integer steps, where $l$ is the azimuthal (or angular momentum) quantum number. This means for a given $l$, $m_l$ can be 0, ±1, ±2, …, up to $l$. This allows for a range of values depending on the orbital in question, making option D correct.
