Chromium is a chemical element with symbol Cr and atomic number 24. It is a steely-gray, lustrous, hard and brittle metal which takes a high polish, resists tarnishing, and has a high melting point. The name of the element is derived from the Greek word χρωμα, chroma, meaning colour,[because many of its compounds are intensely coloured.
