$\huge \hookrightarrow \sf \blue{solution}$

$\rule{190pt}{2.5pt}$

Lithium, potassium and sodium all react with water to form alkanis i.e. lithium hydroxide, sodium hydroxide, potassium hydroxide etc with the liberation of hydrogen gas.

$2 Li + 2 H_{2}O \to \: 2LiOH \: + H_{2} \\ \\ 2Na + 2 H_{2}O \to \: 2NaOH + H_{2} \\ \\ 2K + 2 H_{2}O \to \: 2KOH + H_{2}$

All these metals are having one electron in their respective outermost cells.

Hence the answer will be Yes.
