Azimuthal quantum number defines___________?
Correct answer: C. Angular momentum of an electron
- A. e/m ratio of an electron
- B. Spin of an electron
- C. Angular momentum of an electron
- D. Magnetic momentum of an electron
Explanation
The azimuthal quantum number, l, identifies the subshell and therefore determines the electron's orbital angular momentum, whose magnitude is related to sqrt[l(l + 1)] h/2π. The spin of an electron is described by the spin quantum number, so students may choose b by confusing l with ms.

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.
