${1}^{s t}$ group

#### Explanation:

Sodium is in 1st group in modern periodic table.
$N a \left(11\right) = 1 {s}^{2} , 2 {s}^{2} , 2 {p}^{6} , 3 {s}^{1}$
Last electron enters into s subshell states that $N a$ belongs to S-block.

And, $N a$ has valency of 1 electron so, it belongs to ${1}^{s t}$ group.

In addition to it, $N a$ is a alkali metal. Alkali metals belongs to ${1}^{s t}$ group.
