The formula for iron (II) oxide is FeO. It is a black colored powder, not rust.
iron oxide
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).
One molecule of iron oxide (Fe₂O₃) contains two iron atoms.
Iron(II) oxide is Fe(OH)2 Iron(III) oxide is Fe(OH)3
Iron Oxide Its actually Iron(ii) Oxide there is no such thing as iron oxide.
iron oxide
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.

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
a. 1 iron atom per molecule. in total, two atoms
Ferrous Oxide or Iron 2 oxide
Because zinc in more massive than iron. This assumes that iron in in its 2(+) oxidation state.
A compound is 2 or more elements permanently combined. Rust is a combination of iron and oxygen, both elements- into iron oxide, a compound.
There are a umber of different oxides of iron. It depends of the oxidation state of iron. Hematite is Fe2O3, iron(III) oxide. Magnetite is Fe3O4 (diron(II) diron(III) oxide. There is also FeO, iron(II) oxide.
