Chromium is an essential trace mineral. French chemist Louis-Nicholas Vaquelin discovered it in 1797. Many years later, Walter Mertz, an American physician and research scientist, discovered that chromium played a key role in carbohydrate metabolism. Later researchers agreed that chromium may be the most active component in a group of nutrients that play an important role in blood sugar balance, including nicotinic acid (a version of vitamin B3), and the amino acids that make up glutathione (glutamic acid, cysteine, and glycine).
The stable isotope of chromium is chromium-52. Other isotopes of chromium include chromium-50, chromium-53, chromium-54, and chromium-55, but not chromium-151.
Chromium is a 3d element. chromium is a metal.
Chromium fluorides are: Chromium difluoride: CrF2 Chromium trifluoride: CrF3 Chromium tetrafluoride: CrF4 Chromium pentafluoride: CrF5 Chromium hexafluoride: CrF6
Another chemical name is chromium trichloride or chromic chloride. Chromium(III) chloride is a chemical name as well.
Chromium ore is a source of the metal Chromium.
This compound is chromium hydroxide.
There are three stable isotopes of Chromium 52Cr, 53Cr, and 54Cr.
Some chromium compounds: chromium bromides, chromium chlorides, chromium fluorides, chromium iodides, potassium dichromate, sodium chromate, chromium oxide, chromium sulfide, etc.
Chromium has several valence states, only one of which is Chromium III. States 2, 3, and 6 are most common but 1, 4, and 5 are possible. Total chromium means the amount of chromium in all valence states.
The CrN cation is typically a chromium(III) cation, where chromium has a +3 oxidation state. This means that chromium has lost three electrons and has a charge of +3.
Chromium is in the group 6 (chromium group) of the periodic table.
Cr2O3 is, Chromium (III) oxide or simply Chromium oxide.
