Symbol: Cr; atomic weight: 51.996; atomic number: 24; specific gravity: 7.1. 2. chrome (def 2). Origin Expand 1800-1810 1800-10; chrome + -ium Examples for chromium Expand Isolation and partial characterization of chromium complex from alfalfa. And dragon blood is intensely acidic, which means that you'd want the corrosion resistance offered by high-chromium steel. chromium and nickel can find their way out of steel, but the amounts would be miniscule to nil. Arsenic, radon and chromium are carcinogens, uranium and cadmium can damage kidneys and manganese might have neurological effects. They will measure the ratios of chromium isotopes, and look for one that is characteristic of meteorites. Though native chromium deposits are rare, some native chromium metal has been discovered. chromium is what makes a ruby red, and therefore is used in producing synthetic rubies. Expand British Dictionary definitions for chromium Expand noun 1. a hard grey metallic element that takes a high polish, occurring principally in chromite: used in steel alloys and electroplating to increase hardness and corrosion-resistance.
