Which quantum number determines the orientation of an orbital?

Which quantum number determines the orientation of an orbital?

Step 1: Understand that orbitals are regions in an atom where electrons are likely to be found.
Step 2: Know that quantum numbers are used to describe the properties of these orbitals.
Step 3: Identify the different types of quantum numbers: principal, azimuthal, magnetic, and spin.
Step 4: Recognize that the magnetic quantum number (m_l) specifically relates to the orientation of the orbital in space.
Step 5: Conclude that the magnetic quantum number (m_l) is the one that determines how an orbital is oriented.
