First, this would be an compound, not an element.
Second, it does not exist.
If it did exist it would be iron VI oxide, but iron cannot reach such a high oxidation state.
However, there is Fe2O3, which is iron III oxide.

Fe3O4 is actually a combination of two compounds, Fe2O3 and FeO. The first is called ferric oxide and the second is ferrous oxide. Fe3o4 is also called fericc fero oxide.
The formula FeO3 is written with 4 atoms: 1x Fe and 3x O, but it is NOT a possible iron oxide formula. However some of the possible iron oxides are: FeO, Fe2O3, Fe3O4 having 2, 5, 7 atoms respectively.

FeO3 is a non-exsisting iron oxide.Possible oxides of iron are FeO (ferrous oxide) and Fe2O3 (ferric oxide) and all kind of 'mixtures' of both (oxydules).
FeO2= is a ferric ion where FeO3- is a ferrous ion.
Iron is not a mixture; it is a type of metal, and the most abundant type on Earth. It can also be found in human bodies, fruits, and vegetables.
FeO3 = 103.845 g/mol Fe = 55.845 g/mol (55.845 g/103.845 g) x 100% = 53.8% Fe in 2FeO3

Fe3O4 is actually a combination of two compounds, Fe2O3 and FeO. The first is called ferric oxide and the second is ferrous oxide. Fe3o4 is also called fericc fero oxide.
Any Ferrous mineral is made completely up of Iron Oxide of some form. These are Haematite (FeO2) and Magnetite (FeO3). They are very easily identified because they are magnetic and also have a 'Mamellated' habit (rounded - literally breast-like).
The formula FeO3 is written with 4 atoms: 1x Fe and 3x O, but it is NOT a possible iron oxide formula. However some of the possible iron oxides are: FeO, Fe2O3, Fe3O4 having 2, 5, 7 atoms respectively.
It is an element.
