What Is the F2 Lewis Structure?

The Lewis dot structure for F2, the chemical formula for difluorine, is written with two Fs connected by a single line. Each F is surrounded by three pairs of dots. F is the chemical symbol for the element fluorine.

Each dot represents a valence electron, and the line represents a pair of bonded electrons. The Lewis structure can also be written with lines replacing each pair of electrons or with a pair of dots in place of the line. A valence electron is an electron in the outer shell of an atom. Each molecule of difluorine contains 14 valence electrons, with seven in each atom of fluorine.
