@christopherhoolihan IO3- is the iodate ion, a polyatomic ion, (it's an iodine atom bonded to 3 oxygen atoms and together they pick up an extra electron for a 1- charge). Since there are 2 of them (and they're a 1- each), they give you a total of -2)
Respond to this video... In chemistry, the electrons must balance. The law of conservation of mass says that we don't create matter or destroy matter, we only rearrange it. If the electrons don't cancel out, you have made a mistake and you need to go back and find it.
Thank you very much....It was very helpful..

Will there ever be any electrons left over, suppose they don't cancel out on both sides?
