Alkali metal - Chemical properties | Britannica
5/8/2020· Alkali metal - Alkali metal - Chemical properties: Since the alkali metals are the most electropositive (the least electronegative) of elements, they react with a great variety of nonmetals. In its chemical reactivity, lithium more closely reseles Group 2 (IIa) of the periodic table than it does the other metals of its own group. It is less reactive than the other alkali metals with water
