If the quantum numbers are given as n = 4 and l = 3, what is the maximum number of electrons that can occupy this subshell, considering the formula 2(2l + 1)?

1. 14
2. 12
3. 10
4. 8

Correct answer: 14

Solution

The formula for the maximum number of electrons in a subshell is 2(2l+1). For l = 3 (4f subshell), this becomes 2(2×3+1) = 14 electrons.
