CHEM I NOTES 8 LEWIS STRUCTURES REPRESENTING COVALENT SPECIES Resonance hybrid- weighted average of its contributors - Only one real structure, can be shown by two or more valid structures though - Delocalized e- The arrow shows that these two are valid and mean the same thing, but have differences So the only difference is on what atoms the bonds are made. In finding which model contributes the most when there are more than just two elements (how the professor will ask questions about this) there are three steps/rules. 1.) Full octets are preferred 2.) The model with fewer non-zero formal charges is more likely to be used 3.) Prefer to carry the negative Formal Charge on the atom with the highest
