|Description||Shiny, silvery metal, soft when pure. Resists corrosion due to protective oxide film. Attacked by concentrated acids but not by fused alkalis. Used mainly as alloys and in steel.
With a borax bead test in the oxidizing flame, the bead is yellow when hot, changing to a yellowish green to almost colorless when cold. In a Na2(NH4)(PO4) bead under oxidizing conditions, vanadium is yellow to deep amber (hot) yielding slightly less color on cooling. In the reducing flame, it becomes a dirty green color (hot) and a fine green color when cold.
