Bent The most stable resonance charge has a formal charge that is: 1, 3 The molecular geometry of SO2 is zero on all elements, or has the negative charge on the most electronegative atom. How many single bonds and how many lone pairs does HCl contain? # valence electrons - 1/2(# bonding e's) - (# non-bonding e's) The molecular geometry of CF4 is 1, 2, 8 3, 1 Formula for formal charge
