Chromium (III) sulfide. My friend, I will show you how this is done on practically every problem imaginable. The (III) tells you this Chromium has a charge of +3. The sulfide is the anion for sulfur which means it has a -2 charge (look at what period it lies in. This whole column is . Chromium(VI) phosphate has the chemical formula Cr(PO4)2 because it contains one chromium ion bonded to two phosphate ions. The phosphate ions each have a charge of negative 3, while the chromium ion has a charge of positive 6. For chromium and other transition metals, a Roman numeral refers to the charge of the metal ion.
