The formal charge is the "charge" an element would have in a molecule or ion if all of the bonding electrons were shared equally between atoms. We can draw three inequivalent Lewis structures for carbon dioxide , CO2 . The concepts of formal charge and electronegativity can help us choose the structure that is the most significant representation.1. Assign formal charges to the elements in each of the structures below. A B C Formal ChargeO1CO2 2. The structure that contributes most significantly to the overall electronic structure of CO2 is (A,B, or C) .
