In this video we'll write the correct name for FeP. To write the name for FeP we’ll use the Periodic Table and follow some simple rules.
Because FeP has a transition metal we need to indicate the ionic charge using Roman numerals in parenthesis.
--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 ionic compounds like Iron (III) phosphide, you should check to make sure the charges balance to make sure you have the right name.
