Using Lewis Structures Determining Formal Charge and Oxidation Number Formal Charge(FC) – Charge an atom would have if the electrons in a bond were shared equally between the two atoms FC = # valence e on atom - (# of lone pair e) - (# bonding e associated with the atom) I.e. 1 electron from each bond to each atom in the bond Oxidation Number(ON) Charge an atom would have if the electrons in a bond belong solely to the more electronegative atom ON = # valence e on atom - (# of lone pair e) - (# bonding e associated with the atom) I.e both electrons in the bond go to the more electronegative atom
