WebFormal Charge Questions. So, the practice question ask what is the formal charge on sulfur, S, in a thiocyanate ion, or SCN -. The answer states that the formal charge is 0 and -1. Would this be because having the thiocyanate resonance structure with a +1 formal charge on S and a -2 formal charge on N would be less stable and would only form in ... WebResonance is a way of describing delocalized electrons within certain molecules or polyatomic ions where the bonding cannot be expressed by a single Lewis formula. A … WebThe formal charge of an atom in a molecule is the charge that would reside on the atom if all of the bonding electrons were shared equally. We can calculate an atom's formal charge using the equation FC = VE - [LPE - ½ (BE)], where VE = the number of valence electrons on the free atom, LPE = the number of lone pair electrons on the atom in the ... scrum master infosys
