question about the charge of iron in Fe2O3? | Yahoo Answers
I know that the charge of the Fe cation is 3+, but is this the correct way so find the charge of Fe? O's charge is always 2- & 2- "times" (O)3 = -6 because the charge of an ionic compound is neutral, Fe's charge must be 3+ because 3+ "times" (Fe)2 = 6 O= 6- Fe= 6+ the name of the ionic compound is iron(III) oxide This may sound like a dumb question, but I'm a moron when it comes to chemistry.:)Learn More

Hematite | Fe2O3 - PubChem
Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe3O4) and hematite (Fe2O3). Iron ore is the source of primary iron for the world's iron and steel industries. It is therefore essential for the production of steel, which in turn is …Learn More
