Oxidation state of Iodine
Atoms of Iodine in compounds have an oxidation state of 7, 5, 3, 1, 0, -1.
The oxidation state is the conditional charge of an atom in a compound: the bond in a molecule between atoms is based on the sharing of electrons, thus, if the atom’s charge virtually increases, then the oxidation state is negative (electrons carry a negative charge), if the charge decreases, then the oxidation state is positive.
Oxidation state of an ion I5+ = 5

Valence of I5+
Atoms of Iodine in compounds have valence VII, V, III, I.
Valence of Iodine is an ability of an atom I to build chemical bounds. The valence is based on electronic configuration of atom: electrons participated in chemical bounds are known as valence electrons. In general the valence is:
The number of possible chemical bounds with other atoms
The valence has no sign.
Quantum numbers I 5+
Quantum numbers are defined by the last electron in configuration, for an ion I these numbers are N = 4, L = 2, Ml = 2, Ms = -½
