S: $1 {s}^{2} 2 {s}^{2} 2 {p}^{6} 3 {s}^{2} 3 {p}^{4}$

#### Explanation:

Fill the orbitals from lowest energy to highest energy.

Aufbau's Principle

$s$ orbital can hold up to 2 electrons.
$p$ orbital can hold up to 6 electrons.
$d$ orbital can hold up to 10 electrons.
$f$ orbital can hold up to 14 electrons.
