For other uses, see Chromium (disambiguation). Chromium is a chemical element with symbol Cr and atomic number 24. It is the first element in Group 6. It is a steely-grey, lustrous, hard and brittle metal which takes a high polish, resists tarnishing, and has a high melting point.
Though small quantities of chromium+6 are found in nature, most of the chromium in this form is man-made. Chromium+6 is easily and rapidly reduced to chromium+3 by many chemicals and conditions, so it is not very stable in the environment.
