vanadium |
Also found in: Dictionary/thesaurus, Medical, Encyclopedia, Wikipedia | 0.07 sec. |
vanadiumSilver-white, malleable and ductile, metallic element, atomic number 23, relative atomic mass 50.942. It occurs in certain iron, lead, and uranium ores and is widely distributed in small quantities in igneous and sedimentary rocks. It is used to make steel alloys, to which it adds tensile strength. Spanish mineralogist Andrés del Rio (1764-1849) and Swedish chemist Nils Sefström (1787-1845) discovered vanadium independently, the former in 1801 and the latter in 1831. Del Rio named it ‘erythronium’, but was persuaded by other chemists that he had not in fact discovered a new element; Sefström gave it its present name, after the Norse goddess of love and beauty, Vanadis (or Freya).
