Iron and Oxygen.
Fe2O3 is an oxide of iron.
Fe2O3 is named iron oxide because it contains Fe+ ions.
Iron exists in two oxidation states: Fe2+ and Fe3+. To distinguish between these two oxidation states and to specify which kind of ion will form on dissociation, they are named as Iron II and Iron III. Now, Fe2O3 contains the Fe3+ ion. That is why, it is called iron III oxide.
There are two atoms of iron and three atoms of oxygen in the compound Fe2O3. The mass percent of iron is 69.943%
The chemical formula Fe2O3 is for the chemical compound known as Iron(III) oxide. Its melting point is 2,851 degrees Fahrenheit.
No, iron II oxide should be written as FeO. Fe2O3 is actually iron III oxide.
Fe2O3 is named iron oxide because it contains Fe+ ions.
It is named 'iron three oxide' , not because it combines with three oxygens, but because of the number of electrons on the iron atom involved in combining with another atom. Iron has six (6) electrons in its outer electron shell. Of these six , three are are ionised to form the ion Fe^(3+) ; that is it has 'lost' three electrons. It is this ion and its 'lost' three electrons that form the combination to other atoms. NOT the number of Oxygen atoms.

That compound is Iron Oxide. It contains iron and oxygens.

First of all to correct your formula. It is ' Fe2O3'. Note the use of Capital Letters and the position of the numbers. Secondly ' Fe' is the Latin initials for the word 'iron', which is 'Ferrum'. Hence Fe2O3 is Iron Oxide. Iron exhibits different oxidation states. For given compound of iron, it is correctly named as 'Iron (III) Oxide '. ' Said as 'Iron three oxide '. In everyday terms , this is 'RUST'. Or mined as 'iron ore'. Archaically it would be named as 'Ferric Oxide'. Note the root word 'ferric/ferrum' for iron. Also note the use of Roman Numerals (III) for '3' , to indicate oxidation state. Iron also exhibits different oxidation states. This makes for the other iron compound ' FeO ' , which is Iron (II) Oxide, and is archaically named as Ferrous Oxide. It is in oxidation state (II) '2'. This is much less common and is green in colour.
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.
Iron(II) oxide is FeOIron(III) oxide is Fe2O3
Fe2O3 contains the elements Iron and Oxygen. It would have 2 Iron and 3 oxygen.
b. Fe3 plus ions
Each molecule of iron oxide (Fe2O3) contains two iron (Fe) atoms. The chemical formula indicates that for every three oxygen (O) atoms in the compound, there are two iron atoms. This stoichiometric relationship is crucial for understanding the composition and properties of iron oxide.
The chemical formula Fe2O3 is for the chemical compound known as Iron(III) oxide. Its melting point is 2,851 degrees Fahrenheit.
