What best explains how two oxygen atoms, each with six valence electrons, can bond with each other?
One atom can lose two electrons so that the other atom can gain them and have eight valence electrons
One atom can lose four electrons to the environment so that a total of eight valence electrons remains
Each atom can share two electrons with the other so that each atom has eight valence electrons.
Each atom can lose two electrons so that there is a total of eight valence electrons between the atoms

Each atom can share two electrons with the other so that each atom has eight valence electrons.

Explanation:

A bond between two nonmetals is a covalent bond. In covalent boding, electrons are not transferred(lost/gained) from one atom to the other. Instead, they are shared.

C. Each atom can share two electrons with the other so that each atom has eight valence electrons.
