Re: Determining Resonance
By determining the formal charges on each of the atoms in each variation you can see if one is more stable than others (0 is the most stable).

Re: Determining Resonance
The Lewis Structure with the formal charge closest to 0 is the most stable

Re: Determining Resonance
If you cannot avoid assigning a negative formal charge to an atom, then always draw your structures so that the most electronegative element has the negative formal charge. Ideally though you would want every atom to have zero formal charge, but there are times when that is impossible to achieve.
