What are the chemical properties of chromium?

Chromium is a lustrous, brittle, hard metal. Itscolour is silver-gray and it can be highly polished. It does nottarnish in air, when heated it borns and forms the green chromicoxide. Chromium is unstable in oxygen, it immediatelyproduces a thin oxide layer that is impermeable to oxygen andprotects the metal below.

How did chromium get its name?

Chromium was discovered by French chemist NicolasL. Vauquelin in 1797. He later isolated the element and gave itits name. Chromium gets its name from the Greek word"chroma" meaning color. This name was chosen because theelement can form so many different colored compounds.
