The magnetic quantum number (QN) has its values determined directly by the value of_______________?
Correct answer: B. Azimuthal (QN)
- A. Principal (QN)
- B. Azimuthal (QN)
- C. Spin (QN)
- D. Both A & B
Explanation
The magnetic quantum number, m_l, has values from -l to +l, so its possible values are directly determined by the azimuthal quantum number l. For example, l = 1 gives m_l = -1, 0 and +1. Students may choose the principal quantum number because it limits the possible value of l, but m_l is determined directly by l.

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.
