A bonded atom is considered to "own" all its nonbonding electrons but only half of the bonding electrons because these are shared with another atom. Therefore, the formal charge formula can be rewritten as follows: TC ▼ Part A FC= valence e in free atom nonbonding e shown Formal Charge for H, O, F, O = + 1 2 bonding e shown [)] Due to the small and highly electronegative nature of fluorine, the oxyacids of the this element are much less common and less stable than those of the other halogens. Bonding theory, however, does allow one to propose structures for these acids and use formal charges for the evaluation of these structures. For al molecule of fluorous acid, the atoms are arranged as HOFO.
