How many electrons are around the atom of interest?

Explanation:

And the formal charge is the difference between the atomic number of the element, and the number of surrounding electrons.

Normal rules apply; bonding pairs of electrons are shared between the bound nuclei; lone pairs devolve solely to that particular atom.
