Give a theoretical reason why lithium and oxygen combine in the ratio 2:1

Sagot :

Lithium is in the first column of the periodic table and thus can only form one bond with another atom (its ion is Li+)

Oxygen can form two bonds (as in the dioxygen O2).

Hence if you conbine Li and O it has to be Li2O.
