Formal Charge

Postby Doreen Liu 4D » Tue Oct 29, 2019 10:03 pm

The formal charge equation is FC=V-(L+S/2) where V=valence electrons and L=lone pairs. What is the "S" in the equation?

S = shared electrons. For example, if there is one bond between 2 atoms, then the s=2 (2 shared electrons).

The S in the equation is for shared electrons. For each bond between 2 atoms, there are 2 shared electrons. So if there exists a triple bond, there are a total of 6 shared electrons for those atoms.
