How to Write the Name for Fe2O3

In this video we'll write the correct name for Fe2O3. To write the name for Fe2O3 we’ll use the Periodic Table and follow some simple rules. Because Fe2O3 has a transition metal we need to indicate the ionic charge using Roman numerals in parenthesis for the transition metal. --Keys for Naming Compounds with Transition Metals-- 1) Write the name of transition metal as it appears on the Periodic Table. 2) Write the name and charge for the non-metal. If you have a polyatomic ion, use the Common Ion Table to find and write the formula and charge. 3) Use the total charge on the non-metal (or polyatomic ion) find the charge on the transition metal. 4) After the name for the metal, write its charge as a Roman Numeral in parentheses. Example: Iron (III) chloride ----------------------------- For a complete tutorial on naming and formula writing for compounds, like Iron (III) oxide and more, visit: http://www.breslyn.org/chemistry/naming Writing the name for Fe2O3 is a bit more challenging since Fe is a transition metal. This means you need to use parenthesis and Roman Numerals to show the charge on the Fe atoms. In this case each Fe atom has a charge of +3 so we write Fe2O3 as Iron (III) Oxide.
