Why are lithium and sodium in the same group in the periodic table?

Elements that are in the same group of the Periodic Table have the same number of electrons in their outer energy level. In the case of lithium and sodium, they each have one electron in their farthest shell.

∙ 14y agoLithium and sodium exhibit similar chemical behavior because they have the same number of valence elctrons, 1. Because they each have 1 valence (outer) electron, their electron affinity (how strongly the valence electrons are bound to the atom) is very low. This low electron affinity gives both metals a tendency to give their electron during a chemical reaction, and therefore have similar reactivity. Having 1 valence electron also means that it easily gains a full outer shell (an atom is more stable that way) by giving away that one electron. Having the same number of valence electrons means similar chemical reactivity and behavior.
