The oxidation number of iron depends on the oxide. Bonds between atoms of the same element (homonuclear bonds) are always divided equally. })(window,document,'script','dataLayer','GTM-P247X9K'); In most cases, atoms of the same element in a given compound have the same oxidation states, but each atom can have a different state than the other. The *average* oxidation number is +8/3, as Simonizer1218 pointed out, but it's not really possible for an ion to have a fractional oxidation number. You can understand that the first iron has the number +three because it needs 3 groups ferrocyanide to make the compound.
