Which of the following quantum numbers is used to describe the orientation of an orbital in space?

Question

Quizplus · Accepted Answer

The correct quantum number for describing the orientation of an orbital in space is the magnetic quantum number, often represented as $m_l$. This quantum number can take on integer values from $-l$ to $+l$, where $l$ is the azimuthal (or angular momentum) quantum number. Each value of $m_l$ corresponds to a different orientation of the orbital in space.
