$1 {s}^{1}$

#### Explanation:

Hydrogen is located in period 1, group 1 of the Periodic Table of Elements and has an atomic number equal to $1$.

This implies that the electron configuration of a neutral hydrogen atom must account of a single electron.

This electron will be located on the first energy level, in the $s$ subshell, in the $1 s$ orbital, the sole orbital that exists on the first energy level.

Therefore, the electron configuration for hydrogen will be

$\text{H: } 1 {s}^{1}$
