if iron were to bond with oxygen, what formula would be for each oxidation number of iron?how would each formula be named?please explain!thanks .x
The Iron II ion is an iron ion with a +2 charge. Similarly, the Iron III ion is an iron ion with a +3 charge. If iron bonded with oxygen, it would form Fe2O3 which is rust. In this case, the oxidation number on Fe is +3 and it is -2 on oxygen. This would be called iron (III) oxide. The oxidation number of an ion times the number of the ions must equal zero when added together in a molecule with no charge. In this case, there are 2 iron molecules and each has a positive 3 charge. 2x36. There are three oxygen molecules each with a negative 2 charge. 3x-2-6. 6+-60
Iron (III) has 5 electrons in its outer shell and has a charge of 3- Iron (II) has 6 electrons in its outer shell and has a charge of 2- Iron(II)+Oxygen gas Iron (II) oxide or FeO or Ferrous oxide Iron (III) + Oxygen gas Iron (III) oxide or Fe2O3 or Ferric oxide
