How to Write the Name for FeP
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.
