### Formal Charge

When calculating formal charge, is each single bond counted as one or two shared electrons?

A single bond is counted as one shared electron since it's halved anyway through the equation. (S=2, 2/2=1)

I think it's two shared electrons because in his example SO4 2-, for the oxygen, the equation was FC = 6 - (6 + 2/2) so the numerator in the fraction stands for the number of shared electrons and for SO4 2- the oxygen has a single bond with sulfur so the value of S was 2 since two electrons were shared.

In formal charge, a bond counts as two electrons.

A single bond is counted as one electron although a single bond has a value of 2 electrons because 1 electron goes to one atom and the other electron goes to the other atom.

A single bond is counted as one electron since it is shared hence the electrons in the equation are divided by 2
