+/- 1 (5,7) are the listed oxidation states, but many of these elements that have many electron shells can reach deep into their valance shells for greater oxidation states due to a possibility of electron shielding.
if you mean iodine in its elemental state, the the oxidation state is zero, as for any element in its elemental state, the oxidation state is always zero
The oxidation number of a free element is zero. However, the oxidation number of elements (e.g. iodine) in compounds will not be zero. The actual oxidation number/state can be deduced if the chemical formula of the compound is given.
-3

The Oxidation number is an apparent charge on a single atom in an ion or molecule in Nitrate the Oxidation number of Nitrogen is +5 and -6 for three oxygen atoms (-2 each) so net charge on Nitrate ion is -1.

+3 oxidation state
Fe = +3 oxidation state Cl = -1 oxidation state
The +3 oxidation state is stable-
K = +1 oxidation state Cl = +3 oxidation state O = -2 oxidation state
The highest oxidation state which can be achieved by any element is +8. After all experiments, this state is only found in Osmium, Ruthenium and Xenon. But the synthetic element Hassium is also expected to have this oxidation state.
oxidation state of Fe in FeCl3 is +3. Cl has oxidation number -1 in this case Fe share 3 electrons with Cl so its oxidation state is +3.
