What molecule is created when 4 hydrogen atoms bind with oxygen and 4 electrons

Covalent Bond

Explanation:

Covalent Bond = a chemical bond that involves the sharing of electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding. (dictionary definition)

The oxygen draws the electron density closer to itself than does the hydrogen.
