Sep 24, 2010 · Here's the formula for figuring out the "formal charge" of an atom: Formal charge = [# of valence electrons] – [electrons in lone pairs + 1/2 the number of bonding electrons]

Subtract the number of electrons in the circle from the group number of the element (the Roman numeral from the older system of group numbering, NOT the IUPAC 1-18 system) to …

Identifying formal charges helps you keep track of the electrons. The formal charge is the charge on the atom in the molecule. The term “formal” means that this charge is not necessarily on …
