What is the formula for iron (III) oxide? | Socratic

Nov 10, 2016 ... So, for iron, you multiply its charge of +3 by 2 to get +6 You are taking 2 atoms of iron(III) (or iron atoms with a charge of +3) so it is written as Fe2 . For oxygen, you multiply -2 by 3 to get -6. You have 3 oxygen atoms with a charge of -2, so the answer is Fe2O3 . Check your work by adding up the charges.
