Iron oxide is a chemical compound made of iron and oxygen. It exists in two main forms: Fe2O3 (iron(III) oxide, or hematite) and Fe3O4 (iron(II,III) oxide, or magnetite).
Whenever water or air is around iron for a while it can rust because the iron bonds to the oxygen forming iron oxide.
iron oxide
iron can make 6 electrons which have outer electrons.iron mixed with oxide will make a gas called iron oxide. iron oxide is used a lot in lab research and testing.
One molecule of iron oxide (Fe₂O₃) contains two iron atoms.
Basically there are 2 forms of iron:iron 2+ and iron 3+ Iron 2 oxide, basically is Fe2+ in order to stabilize it you need 2- which is exactly one oxygen ion therefore we get FeO While iron 3 oxide is Fe3+ in order to make a stable compound we need 2 Fe 3+ along with 3 O 2- which gives us +6 and -6 therefore a stable compound which is Fe2O3 the hydrated form of iron 3 oxide is rust

No elements are made up of a compound. I think you mean 'Which elements make up iron oxide?', and the answer to that is iron and oxygen.
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.

Iron and oxygen
Fe3O2. But it's not right! Oxygen forms a 2- ion and iron can be 2+ or 3+. So the formulae of iron oxide can be FeO or Fe2O3.
Iron (II) oxide.FeO=====( older name still in use; ferrous oxide )
One molecule of iron oxide (Fe₂O₃) contains two iron atoms.
Iron(II) oxide is Fe(OH)2 Iron(III) oxide is Fe(OH)3
