Since iron oxide is made from TWO elements (Fe, and O), it is a compounds and so you have a MOLECULE, not an atom of iron oxide.
Each molecule of iron oxide Fe2O3 contains 2 atoms of iron and 3 atoms of oxygen, making a total of 5 atoms in one molecule.
Rusting of iron is a chemical change because it involves a reaction with oxygen to form iron oxide. Melting of iron is a physical change because it does not involve a change in the chemical composition of the iron.
Magnetite belongs to the spinel group of minerals
One example of a compound containing iron is iron oxide, which has the chemical formula Fe2O3. Iron oxide is commonly found in nature as rust and is used in various applications, including as a pigment in paints and ceramics.
One molecule of iron oxide (Fe2O3) contains two iron atoms per molecule. So, for every molecule of iron oxide, there are two iron atoms, which means one iron oxide molecule contains two iron atoms.
One molecule of iron oxide consists of one iron atom and one oxygen atom. Therefore, the total number of atoms in one molecule of iron oxide is two.
One molecule of iron oxide (Fe₂O₃) contains two iron atoms.

Iron oxide has most often has 2 atoms of iron per molecule.There are two forms of iron oxide, FeO (which has one iron atom) and Fe2O3.Iron can take on a valence of II or III. Confusing. There are actually addition formulas for other iron oxides, too, including magnetite (Fe3O4).The most common form is the Fe2O3 structure, which is the familiar iron rust.
It depends which iron oxide you mean. Iron(II) Oxide, FeO, which is black and has 1 oxygen molecule bonded with an iron one . Iron(III) Oxide (Fe2O3) ie rust has 2 iron molecules bonded to 3 oxygen molecules.
Well, iron oxide is a combination of iron(Fe) and oxygen (O). We know Fe(III) has a charge of +3 and oxygen has a charge of -2, so we must balance them. Their LCF is 6, so to balance them, we must have 2 atoms of iron (3x2=6) and 3 atoms of oxygen (-2x3=-6). Therefore we know that there are 2+3 atoms in this molecule, so 6 atoms in the molecule.
In iron(III) oxide (Fe2O3), there are two iron atoms per molecule. Since the atomic weight of iron is approximately 55.85 g/mol, the total weight of iron in one mole of Fe2O3 would be around 111.7 g.
Rust is generally thought of as a compound of iron and oxygen. So, there are two types of elements in rust. Additionally, because iron is a metal and oxygen is a non-metal, those two elements combine ionically, so it is incorrect to consider a representative particle of rust a molecule. It is accurate to refer to it as a formula unit, or simply a particle.
The right question should be: Does one mole of iron weigh the same as one mole of iron oxide? The answer is NO, Iron Oxide weighs more.
