The letters s p d and f are used to represent which quantum numbers________________?
Correct answer: B. Azimuthal
- A. Principal
- B. Azimuthal
- C. Magnetic
- D. Spin
Explanation
The letters s, p, d and f represent subshells identified by the azimuthal quantum number, l. They correspond to l = 0, 1, 2 and 3 respectively. Students may choose a because the principal quantum number identifies the main shell, but it is written as n, not s, p, d or f.

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.
