Answer
(a) As alkali metals are very reactive metals, hence they are kept in inert solvents.
(b) As alkali metals and halogens are very reactive, hence, they do not occur free in nature.
(c) As alkali and alkaline earth metal have 1 and 2 valence electrons respectively hence, they tend to donate the valence electrons to attain a stable configuration and form electrovalent compounds.
(d) As the outermost orbits of inert gases are completely filled and they are in a stable state hence they do not form compounds.
