Chromium is a chemical element which has the symbol Cr and atomic number 24. It is the first element in Group 6. It is a steely-gray, lustrous, hard and brittle metal[2] which takes a high polish, resists tarnishing, and has a high melting point. The name of the element is derived from the Greek word ?????, chr?ma, meaning colour,[3] because many of its compounds are intensely coloured.
