The s-block elements share electron configurations. s-block elements are the elements found in Group 1 and Group 2 on the periodic table. ... Because they have 2 valence electrons they are less reactive than group 1. Hydrogen is a nonmetal grouped with the alkali metals because it has one electron in its valence shell....✌☺✌
