Stable Vs. Formal

Postby Shibhon_Shepard » Tue Nov 13, 2018 5:09 pm

Is there a difference between the stable charge and the formal charge? if they are explain please and thank you.

I think stable charge refers to the formal charge of the most stable structure for the specific molecule

Formal charge would refer to the charge of each individual atom and the overall number of electrons an atom owns in a molecule. I believe stable charge would just be the most stable form of the entire molecule.

Formal charge is the electric charge of an atom in a molecule assigned on the assumption that the bonding is nonpolar covalent. It is calculated by FC = number of valence electrons in the free atom - (number of lone-pair electrons + 1/2 * number of shared electrons). Stable charge refers to the formal charge of the most stable structure of the given molecule (closest to 0).

Formal charge is the overall charge of an atom or molecule; the most stable charge for a molecule is generally the formal charge closest to 0.
