* Fluorine is a nonmetal. Nonmetals tend to gain electrons to achieve a stable electron configuration.
* Fluorine has 7 valence electrons. It needs one more electron to have a full octet like a noble gas.
* When two fluorine atoms bond, they share their electrons equally. This is called a covalent bond. Since each atom is equally pulling on the shared electrons, there is no net gain or loss of electrons for either fluorine atom.
Therefore, F2, a fluorine molecule, has no charge. It is neutral.
