*Please select more than one item to compare Covalent compounds For example, pyrite, which is also called fool’s gold owing to its brassy yellow colour, is a sulfide of iron with the formula FeS 2. How do we know for certain protons and electrons exist? The formula for chromium(III) sulfide is Cr2S3. remember, that comes from the Roman numeral. Chromium (VI) can be reduced to the more stable chromium (III) in the presence of reducing agents (e.g. The phosphate ions each have a charge of negative 3, while the chromium ion has a charge of positive 6. Step #4 - since a formula must have zero total charge, you write the formula Fe2S3. (1) Chromium occurs in the environment predominantly in one of two valence states: trivalent chromium (Cr III), which occurs naturally and is an essential nutrient, and hexavalent chromium … Chemical suffixes.
