The Fascinating World of Chromium

Chromium, symbolized as CR, is a gray, shiny, hard metal with a high melting point. Discovered in 1761, it was isolated by Louis Nicolas Vaculin. Chromium is used in metal alloys like stainless steel for its corrosion resistance and in electroplating for surface coating. It also serves as a pigment due to its vibrant colors, used in various applications from school bus paint to military vehicle camouflage.
