How to Write the Name for Fe3O4

In this video we'll write the correct name for Fe3O4. To write the name for Fe3O4 we’ll use the Periodic Table and follow some simple rules. Because Fe3O4 has a transition metal we need to indicate the ionic charge using Roman numerals in parenthesis. Fe3O4 is difficult because we come up with a fractional ionic charge, which doesn't make sense. The reason is that Fe3O4 is made up of FeO and Fe2O3. For more information, see: https://en.wikipedia.org/wiki/Iron(II... --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 (II, III) oxide and more, visit: http://www.breslyn.org/chemistry/naming Drawing/writing done in InkScape.
