Question

which characteristic is given by the angular momentum quantum number?
○ orbital size
○ orbital mass
○ orbital shape
○ orbital orientation

Explanation:

size is from the principal quantum number, orbital orientation from the magnetic quantum number, and orbital mass is not a property defined by quantum numbers for atomic orbitals.
