Chromium Wikipedia

Chromium is a chemical element with symbol Cr and atomic number 24 It is the first element in group 6 It is a steelygrey 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 χρῶμα chrōma meaning color Chromium is a chemical element with symbol Cr and atomic number 24 It is the first element in group 6 It is a steelygrey 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 χρῶμα chrōma meaning color
