What is the formal charge on the iodine atom in the iodate ion, IO₃^-?

Question

Quizplus · Accepted Answer

The formal charge on the iodine atom in the iodate ion (IO3-) can be calculated using the formula: Formal charge = Valence electrons - (Nonbonding electrons + 1/2 Bonding electrons). Iodine has 7 valence electrons, it is bonded to three oxygen atoms (with two electrons shared in each bond, totaling 6 bonding electrons), and it has no nonbonding electrons. Thus, the formal charge = 7 - (0 + 1/2*6) = 7 - 3 = +2.
