What is the difference between resonance and formal charge?
Q. According to my book, resonance occurs when several equivalent Lewis formulas can be written... But the actual structure of the compound is somewhat in between the residence (instead of a double and single bond it's really two 1.5 bonds) Fastforward to Formal Charge and it says that you have to pick one of the formal charges (the one that is closest to zero and has the negative charge on atoms that are highly electronegative) thus canceling out the definition of resonance

A. Some Lewis Structures like Ozone O has several resonances like a ring structure, double bonds on the right or left etc. Formal charge calculation is used to determine is which structure is more correct. The general formula for calculating Formal Charges is F = Ev - (Eu + 1/2Ep) * F is the formal charge * Ev is the number of valence electrons in the bare atom * Eu is the number of electrons in lone pairs on the atom in the Lewis structure * Ep is the number of electrons in bonded pairs on the atom in the Lewis structure The rule of thumb is to make all formal charges 0 or close to 0.
