The purpose of formal charges is to compare the difference between the number of valence electrons in the free atom and the number of electrons the atom "owns" when it is bonded. The smaller the difference, the "happier" (more stable) the atom is. The atom owns all of the lone pair (non-bonding) electrons and half of the ...At times, the resonance structures are not equivalent, and it is essential to determine which one (s) describes the best actual bonding.
