We can draw three inequivalent Lewis structures for the arsenite ion , AsO33- . The concepts of formal charge and electronegativity can help us choose the structure that is the best representation.1. Assign formal charges to the elements in each of the structures below. Note: Count oxygen atoms starting from the left for each structure. ABCFormal ChargeAsO1O2O3-200-1-10-1-10-1-1-12 . The best Lewis structure for AsO33- is .
