### Formal Charge Equation

Is there another way to determine the formal charge of an atom without the equation?

A short cut that might help when calculating formal charge is counting the number of bonds and unpaired electrons and subtracting that number from the number of valence electrons the atom has.

One way that I like to think about it is subtracting the valence electrons of the atom in the ground state from the number of electrons it has around it. For bonds, this would mean only one electron in that bond is coming from the atom you're calculating the formal charge for.

just count the number electrons and dashes and subtract it from the atom's number of valence electrons
