Why do two fluorine atoms bond together?
Two fluorine atoms bond together to form the fluorine molecule because both those atoms can obtain a full octet by the sharing of two electrons.
When two fluorine atoms come together, they each share one of their 7 valence electrons to form a nonpolar covalent bond. A nonpolar covalent bond implies that both electrons that form the bond between the fluorine atoms are shared equally.
When electrons are shared equally, they spend the same amount of time on both atoms that form the bond, that is why the fluorine molecule, or
