the common name for most iron oxides is rust
I am going to assume you meant ferrous oxide. Ferrous oxide is also known as Iron(II) oxide and has the formula unit FeO. The oxidation number of iron in iron(II) oxide is +2.
This is iron II, III oxide and features iron in both the 2+ and 3+ oxidation states.
The oxidation number of Fe in FeO (iron oxide) is +2. This is because oxygen typically has an oxidation number of -2, and in a neutral compound like FeO, the oxidation numbers must balance out to zero.
The oxidation number of iron in ferrousofericoxide (Fe3O4) is a combination of Fe(II) and Fe(III) ions. The Fe(II) ions have an oxidation number of +2, while the Fe(III) ions have an oxidation number of +3. Each formula unit of Fe3O4 contains two Fe(III) ions and one Fe(II) ion, resulting in an average oxidation number of +2.67 for iron in this compound.

The oxidation number of iron is +2 (Fe2+), and the oxidation number of oxygen is -2 (O2-). In iron(II) oxide (Fe2O3), which has two iron ions and three oxygen ions, the overall charge must balance to zero, so the oxidation number of iron is +3.
The oxidation number of iron in ferric oxide (Fe2O3) is +3. This is because oxygen typically has an oxidation number of -2, and since there are 3 oxygen atoms in Fe2O3, the total oxidation number from oxygen is -6. In order for the compound to be neutral, the oxidation number of iron must be +3 to balance out the -6 from the oxygen atoms.
The oxidation number of NO, nitrogen oxide, is +3.
The oxidation number of Fe in FeO (iron oxide) is +2. Oxygen is typically assigned an oxidation number of -2, so since FeO is a neutral compound, the oxidation number of Fe must be +2 to balance out the charge of the oxygen.
The oxidation number for lithium is +1 and for oxygen is -2. In lithium oxide (Li2O), lithium has an oxidation number of +1 and oxygen has an oxidation number of -2. Therefore, the change in oxidation number for lithium oxide is -1 for lithium.
You have answered the question for yourself.!!!!! Iron (III) Oxide [ Fe2O3] has the oxidation number of '3'. Written in Roman Numerals ' III ' . An atom of iron has 6 electrons in its outer most energy (valence) shell. Of these six electrons only '3' are involved in combining with another atoms. This other '3' remain uncombined. Similarly Iron (II) Oxide NB Iron as all the other Transition [ 'd' block ] elements, exhibits variable oxidation numbers. NNB When you read Roman Numerals in a chemical name formula, it indicates the oxidation state. NNNB Archaically Iron(II) oxide is Ferrous Oxide , and Iron(III) oxide is Ferric oxide. NNNNB Potassium permanganate has the manganese in oxidation state '7', written as Potassium manganate(VII) [ KMnO4] .
Because zinc in more massive than iron. This assumes that iron in in its 2(+) oxidation state.
