Hint for Naming Fe2O3

With Fe2O3 we have a transition metal and a non-metal. This is a binary ionic compound.

  • Name the metal as it appears on the Periodic Table.
  • Name the non-metal (Oxygen) by replacing the ygen with ide.
  • Look at the chemical formula to find the charge for Iron. O has an ionic charge of -2 but we have three of them. That means we have a total of -6. Since we have two Fe atoms each one will need to be +3 to give us a +6 and balance the charges for the compound.
  • We write (III) after the element symbol for iron to show that it has a +3 charge.
