WebVandaag · Formal charge for Nitrogen atom = 5 – 0.5*6 – 2 = 0. Formal charge for each Fluorine atom = 7 – 0.5*2 – 6 = 0. As we can see, all the atoms inside the NF3 molecule have the least possible formal charge values. Therefore, we have attained our most perfect Lewis Structure diagram. how do scientists control lionfish
