Vanadium
noun, Chemistry.
1.
a rare element occurring in certain minerals and obtained as a light-gray powder with a silvery luster or as a ductile metal: used as an ingredient of steel to toughen it and increase its shock resistance. Symbol: V; atomic weight: 50.942; atomic number: 23; specific gravity: 5.96.
noun
