Magnetic quantum number specifies___________?
Correct answer: C. Orientation of orbitals
- A. Size of orbitals
- B. Shape of orbitals
- C. Orientation of orbitals
- D. All of the above
Explanation
The magnetic quantum number, ml, gives the orientation of an orbital in space within a subshell. The principal quantum number determines orbital size and the azimuthal quantum number determines shape, so students may choose d by assigning all orbital properties to ml.

About Quantum Numbers
Quantum numbers describe an electron's energy level, subshell, orbital orientation and spin. You examine the principal, azimuthal, magnetic and spin quantum numbers, their allowed values, orbital capacity and how they determine electronic configurations and distinguish electrons within an atom.
