You use it on every single element
antony
When naming compounds. For example, Iron (VI) Carbonate.
I'm not sure if it has a name, but most call it 'naming ionic compounds with multiple ion charges'. I think that what you're looking for is the "Stock System."
No, Roman numerals are not used in covalent compounds. Roman numerals are used in the naming of ionic compounds to indicate the charge of a transition metal ion. In covalent compounds, the elements are combined through sharing of electrons and do not involve ions with specific charges.
Chemical compounds are not named in Roman numerals!

You must use roman numerals to indicate which oxidation state the element is in when that element is in a compound.

You'll see a lot of Roman Numerals in Chemistry. When naming compounds, you'll need to know the difference between Iron (IV) Carbonate and Iron (II) Carbonate, for example. In plays, often acts and scenes are organized with Roman Numerals. (Act III, Scene I). And, in all honesty, lots of people will use Roman Numerals just to make something look fancier. Its typically a good idea to know at least the first five roman numerals off the top of your head.
Its there too tell you the charge of the compound.
