Drawing the Lewis structure of the … WebFormal charge. In chemistry, a formal charge ( F.C. or q* ), in the covalent view of chemical bonding, is the hypothetical charge assigned to an atom in a molecule, …
WebApr 6, 2015 · Formal Charge = [# valence electrons on neutral atom] – [ (# lone electron pairs) + (½ # bonding electrons)] Valence electrons = corresponds to the group number of the periodic table (for representative elements). Lone Pairs = lone electrons sitting on the atom. Each electron counts as one and so a pair counts as two.
WebThis gives the formal charge: Br: 7 – (4 + ½ (6)) = 0. Cl: 7 – (6 + ½ (2)) = 0. All atoms in BrCl 3 have a formal charge of zero, and the sum of the formal charges totals zero, as it must in a neutral molecule.
