The central atom in the hypothetical iodite ion would be surrounded by 10 electrons
The formula for the iodite anion is IO2-
Iodite is the hypothetical polyatomic ion, IO2-. Cobalt(III) carries a 3+ charge. Therefore Cobalt(III) iodite: Co(IO2)3
IO- is an ion, not a compound. it is called the hypoiodite ion.

Reductant Iodide (I-) can be oxidised to other (more postive) oxidation numders by loosing electrons to the oxidant. Depending on the oxidant's strength this can change to the following numbers: 0 (zero) in I2 , and +1, +2, +3, +4 (in hypoiodite IO-, iodite IO2-, iodate IO3-, periodate IO4- respectively)

The hypothetical acid iodous acid, HIO2, would be made from the hypothetical iodite ion, IO2-.
The anion periodate - IO4 (from the periodic acid HIO4); the charge is -1.
Al(IO2)3 This salt is hypothetical no iodite salts have been isolated.Chlorites are known and a bromite.
Iodine can form at least three oxides, with formulas IO2, I2O5, and I4O9. The first one of these is sometimes written as a dimer, with formula I2O4.
IO2 is the chemical formula of iodine dioxide.
