Noun
A rare element of the nitrogen-phosphorus group, found combined, in vanadates, in certain minerals, and reduced as an infusible, grayish-white metallic powder. It is intermediate between the metals and the non-metals, having both basic and acid properties. Symbol V (or Vd, rarely). Atomic weight 51.2.

Ammonium vanadate(V) (NH 4 VO 3 ) can be successively reduced with elemental zinc to obtain the different colors of vanadium in these four oxidation states. Source: Internet
As superconducting vanadium is warmed toward its critical temperature, its heat capacity increases massively in a very few degrees; this suggests an energy gap being bridged by thermal energy. Source: Internet
Chlorides of vanadium were generated in 1830 by Nils Gabriel Sefström who thereby proved that a new element was involved, which he named "vanadium" after the Scandinavian goddess of beauty and fertility, Vanadís ( Freyja ). Source: Internet
During combustion, vanadium oxidizes and reacts with sodium and sulfur, yielding vanadate compounds with melting points as low as 530 °C, which attack the passivation layer on steel and render it susceptible to corrosion. Source: Internet
Amanita muscaria and related species are known as effective bioaccumulators of vanadium ; some species concentrate vanadium to levels of up to 400 times those typically found in plants. Source: Internet
