The maximum number of electron in a sub shell with ? = 3fs______________?
Correct answer: C. 14
- A. 6
- B. 10
- C. 14
- D. 18
Explanation
For l = 3, the subshell is an f subshell and it contains 2l + 1 = 2(3) + 1 = 7 orbitals. Each orbital holds 2 electrons, so the maximum is 7 x 2 = 14 electrons. Students may choose 18 because 18 is the maximum number of electrons in a complete shell with n = 3, not in an f subshell.

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.
