Question

In forming oxygen molecule, ______ electrons are shared by each atom of oxygen.

Answer 1

In forming oxygen molecule, two electrons are shared by each atom of oxygen.

Explanation:

An oxygen atom has six valence electrons and needs two more to achieve a stable octet. When two oxygen atoms combine, each shares two of its own electrons with the other. This mutual sharing of four total electrons forms a stable covalent double bond (O = O).
