Overview
Chromium is a lustrous, hard metal known for forming corrosion resistant alloys and colorful compounds such as chromiumIII and chromiumVI species.
Properties
It has high melting point, forms a protective oxide layer and displays multiple oxidation states with distinct chemical behavior.
Occurrence and Uses
Chromium is used in stainless steel, electroplating, pigments and refractory materials and is mined from chromite ores.
Isotopes and Safety
Stable isotope Cr 52 is common; hexavalent chromium compounds are carcinogenic and require strict industrial hygiene and regulatory controls.
