In #"dioxygen gas"# there are TWO bonding electron pairs.......four electrons in total.

Explanation:

The typical Lewis structure of the #O_2# molecule is as #O=O#. Each oxygen atom is conceived to be #sp_2# hybridized, and there are two lone pairs around each oxygen atom in the molecule.

To be a bit more systematic, each oxygen atom has 8 electrons. Two of these electrons are inner core, and this leaves 6 electrons to distribute around each atom, and this fills the three #sp_2# orbitals.
