This is because of the increase in atomic size and increasing ease with which an electron can be removed from the outermost shell. The reactivity of s-block elements increases down the group. Therefore, they can form mono-positive and dipositive cations. These electrons can be easily removed due to the low value of ionization potential. The s-block elements contain one or two electrons in their outermost shell. The melting and boiling points of alkaline earth metal are shown below: The melting and boiling points of alkali metals are shown below: Similarly, their melting and boiling points decrease down the group due to an increase in size. The s-block elements have low melting and boiling points due to their large sizes.
