The metallic element and its trivalent compounds are generally safe, but hexavalent chromium compounds are toxic and carcinogenic, requiring careful handling.
It comes from the Greek word 'chrōma', meaning colour, because its compounds are vividly coloured (e.g., chromium oxide is green, potassium chromate is yellow).
