Calculating Formal Charge The formal charge (FC) of an atom in a molecule or polyatomic ion is the hypothetical charge the atom would have if we could redistribute the electrons in the bonds evenly between the atoms. The calculated formal charge for an atom is not the actual charge of the atom in the molecule (or polyatomic ion). Formal charge is only useful as a bookkeeping procedure. How to Calculate Formal Charge: Formal charge is the result of taking the number of valence electrons of a neutral atom and subtracting the nonbonding electrons (NBE), and then subtracting one half of the bonding electrons (BE). Formal Charge - #valence e-#nonbonding e-#bonding e FC-#VE-#NBE-%#BE Formal charge calculation for sulfur (S) in SO₂ Sa FC (on S) = 6-2-(6)=+1 DOUBLE CHECK formal charge calculations by determining the sum of the formal charges for the whole structure. • The sum of the formal charges of all atoms in a molecule must be zero. • The sum of the formal charges in a polyatomic ion, should equal the charge of the ion. -S=0: FO Structure +1 Formal charge :Ö: -1
