Fe2O3
+3 for each Fe
-2 for each O
feo2 feo3 feo4
Fe2O3 is named iron(III) oxide because it contains iron in its +3 oxidation state. The Roman numeral III in parentheses indicates the oxidation state of iron in the compound. Additionally, the name helps differentiate it from other iron oxides like FeO (iron(II) oxide) and Fe3O4 (iron(II,III) oxide).
It stands for the charge on the iron ion. In Iron III oxide iron has a 3+ charge.
No such compound exists. If it did it would be iron VI oxide, but iron cannot reach such a high oxidation state. Perhaps you mean Fe2O3, iron III oxide.
The formula for iron using the highest oxidation number is Fe2O3, which is iron(III) oxide. In this compound, iron is in the +3 oxidation state.

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.
The formula for iron using the highest oxidation number is Fe2O3, which is iron(III) oxide. In this compound, iron is in the +3 oxidation state.
Oxidation or rust
The oxidation number of iron in ferrousofericoxide (Fe3O4) is a combination of Fe(II) and Fe(III) ions. The Fe(II) ions have an oxidation number of +2, while the Fe(III) ions have an oxidation number of +3. Each formula unit of Fe3O4 contains two Fe(III) ions and one Fe(II) ion, resulting in an average oxidation number of +2.67 for iron in this compound.
Iron(II) oxide is Fe(OH)2 Iron(III) oxide is Fe(OH)3
No. Iron III oxide is an ionic compound. This is due to the large difference in electronegativity between oxygen and iron. If the electronegativity difference is greater than 2.0 a compound is generally ionic. The difference between iron and oxygen is 2.61.
FeO for ferrous oxide, ( iron(II) oxide); Fe2O3 for ferric oxide, (iron(III) oxide) and Fe3O4 for ferrous ferric oxide, (iron (II,III) oxide)
The name iron III oxide shows that you have two types of ion in the compound, the iron III ion (Fe3+) and the oxide ion (O2-). What you need to do is find what ratio to combine the ions in so that the positive and negative charges cancel out to zero. One way of doing this is to switch the numbers of each ion's charge, and assign it to the opposite ion, so in this case you get 2 Fe3+ ions and 3 O2- ions. So the formula is Fe2O3
