WebAlkali metals have one electron in their valence shell. The outer electronic configuration of alkali metals is ns -1. For example, the electronic configuration of lithium is given as 1s 2 s 1. They tend to lose the outer shell electron to form cations with a charge of +1 (monovalent ions). So their oxidation state is +1. WebWhy do alkali metals give characteristic flame colouration?
