#### Explanation:

The alkali metals or group 1A family have only one electron in their valance shell.

Sodium for example has 11 electrons 2 are in the first* filled shell , 8 are in the second filled shell. This makes a total of 10 in filled shells leaving only one electron in the outer shell, where the valance electrons are located.

$1 {s}^{2} 2 {s}^{2} 2 {p}^{6} 3 {s}^{1}$ is the electron configuration of Sodium.

All of the alkali metals follow the same pattern.
