The most stable resonance charge has a formal charge that is: 7- (.5)(2) - 6 =0 # valence electrons - 1/2(# bonding e's) - (# non-bonding e's) Formula for formal charge The molecular geometry of SO2 is How many single bonds and how many lone pairs does HCl contain? The molecular geometry of CF4 is Bent 18 What is the mathematical process of finding the formal charge of Cl in HCl?
