To compute the formal charge you must start with a Lewis structure complete with bonding electrons and lone pairs. The charge assigned to an atom in a molecule is formal charge. formal charges are +1 for S, and –1 for the oxygen atom with a single bond to S. The low formal charges of S make structures 2 and 3 more stable or more important contributors. A formal charge can be defined as the electrical charge of an atom within a molecule, and calculated by determining the total number of valence electrons minus half the total electrons located in a shared bond minus the number of electrons not in the molecule. EDIT again: 4 electrons contained in the N=O double bond. 2 more in the lone pair, and one single electron = 7. Formal Charge. Answer to: Draw all possible resonance structures for NO2-.
