Lesson 3 (Naming): Molecular Compounds IUPAC & Classical

Classical Naming of Ionic Compounds 

-       We can use a suffix instead of a roman numeral to show whether the metal in an ionic compound has the higher ionic charge from the periodic table or the lower ionic charge.

-          We use the root latin names for the metal from your reference sheet

-          We put a suffix “ic” or “ous” on the root name to show if the metal has the lower or higher charge from the periodic table.

-          if it ends in “ic”, the metal has the higher charge from the periodic table

-          if it ends in “ous”, the metal has the lower charge from the periodic table
