The S-Block Elements
Why are alkali metals not found in nature?
Alkali metal has one electron each in the valence subshell of their atoms. Since they have only one electron in valence subshell, therefore, they lose easily, owing to their low ionisation energies. Therefore, alkali metals are highly reactive chemically and do not exist in the free or native state.
