Formal Charge terms
What equation should we use to calculate formal charge and what do the terms mean?

Re: Formal Charge terms
I like to do the following formula to calculate it:
formal charge = valence electrons of the atom - (lone pairs + .5* bonded electrons).
formal charge = valence electrons of the atom - (lone pairs + .5* bonded electrons).

Re: Formal Charge terms
Hi Maria,
This is what each of the terms mean:
FC (Formal Charge)- the charge that is given to a molecule, assuming equal sharing of electrons in chemical bonds.
VE (Valance Electrons)- outer shell electrons that participate in bonding.
In order to find the VE, in the first and second period, the number of valance electrons is the period number. For periods 13-18, the number of valance electrons is that number minus 10.
LP (Lone Pairs)- a set of valance electrons that are not shared with another atom.
BE (Bonded Electrons)- the electrons, in the outer shell, which can participate in bonding.
