The sharing of electrons between atoms
There are two ways to answer this. The first way would be for a person who is not very familiar with chemistry, and the second for someone who is. First description: A covalent bond can be best described as a bond between to atoms which share electrons. This is different from ionic bonds where electrons are taken from one atom and placed onto another. Second description: A covalent bond is an overlap of electron densities of same sign or potentialities (two bonding orbitals as opposed to antibonding) , which can be described by their orbital wavefunctions. I hope one of these answers suits you.

What best explains how two oxygen atoms each with six valence electrons can bond with each other?

The sharing of electrons between atoms
atoms and molecules are always moving
An atom represents the smallest particle that retains unique chemical properties.

Because , Carbon has 4 valence electrons , which is the best number of valence electrons , because it can easily give or take or share that number . . (: ~ Hope this heelps . <3
Two molecules of ammonia contain 6 hydrogen atoms.
molecules
A core of protons and neutrons surronded by electrons.
Atoms and molecules are always in motion
This is the atomic orbitals theory.
