vanadium

Also known as V, element 23, 23V

Vanadium is a chemical element; it has symbol V and atomic number 23. It is a hard, silvery-grey, malleable transition metal. The elemental metal is rarely found in nature, but once isolated artificially, the formation of an oxide layer (passivation) somewhat stabilizes the free metal against further oxidation.

OverviewAI-generated

Vanadium is a chemical element with the symbol V and atomic number 23. It has a mass of 50.9415 and an electron configuration of [Ar] 3d³ 4s². The element exhibits oxidation states of 3, -1, 1, and 2, with an electronegativity of 1.63. Its ionic radius is 0.76.

Vanadium melts at 1887 and boils at 3377. It was discovered in 1801. The element is referenced by 1,425 other encyclopedia articles. In chemical databases, it is associated with the CID 23990 and the InChIKey LEONUFNNVUYDNQ-UHFFFAOYSA-N. PubMed records 16,020 entries for the query "vanadium."

Spanish-Mexican scientist Andrés Manuel del Río discovered compounds of vanadium in 1801 by analyzing a new lead-bearing mineral he called "brown lead". Though he initially presumed its qualities were due to the presence of a new element, he was later erroneously convinced by French chemist Hippolyte Victor Collet-Descotils that the element was just chromium. Then in 1830, Nils Gabriel Sefström generated chlorides of vanadium, thus proving there was a new element, and named it "vanadium" after the Scandinavian goddess of beauty and fertility, Vanadís (Freyja). The name was based on the wide range of colors found in vanadium compounds. Del Río's lead mineral was ultimately named vanadinite for its vanadium content. In 1867, Henry Enfield Roscoe obtained the pure element.
