Because the alkali metals are all in group 1 of the s-block, they all have one valence electron. Thus their electron configurations all end with Ns1, where N refers to the quantum level. Hydrogen ends with 1s1, Lithium with 2s1, etc.

∙ 9y agoAll alkali metals have one valance electron in an S-orbital. The major difference is the distance between the Orbital and the Nucleus.
Li is 2S1
Na is 3s1
K is 4s1
