Formal charge equation
Can the equation for formal charge be rewritten as Valence electrons - (dots + lines)= formal charge?

Re: Formal charge equation
I say to safe just stick to the equation that Lavelle gave. From what I heard though from some T.A. and U.A's, it is best to just use the short cut method so that you can focus on arranging the lewis structure in least charged state possible where(if need to) the atom with the highest electronegativity has the (-) charge. The short cut way if you don't know is just to count how many "things" are around an atom and compare it to the number of valence electrons the element is supposed to have.

Re: Formal charge equation
Yes, it works, because it is actually equivalent to the formal formula, numerically. As long as not written formally in exams, I think that using this equation instead is much faster in calculation and harder to make mistakes.
