For example, chromium can form Cr2+, Cr3+ or Cr6+. Thus when you see the name of a compound involving chromium, it should have the oxidation number written in Roman numerals in parentheses. For example, if Cr2+ formed a compound with one atom of oxygen, the name would be chromium(II) oxide, and the formula would be CrO. Best Answer: Roman numerals are used when the metal has multiple oxidation numbers, to represent its apparent charge. For example, "copper oxide" describes more than one compound. "Copper (I) oxide" (or "cuprous oxide") is when the copper has an oxidation number of 1. It has the chemical formula Cu2O.
