Characteristics of element:
Pictures: Vanadium is found in several forms including foil, granules,
powder and rods.
Here is vanadium foil.
Vanadium powder
Vanadium granules
And finally, vanadium rod.

 Appearance:
Pure vanadium is classified as a greyish silvery metal; it is soft and ductile,
that is, it conducts electricity. When it is subjected to alkalis, sulphuric acid,
hydrochloric acid, or salty water, it does not corrode (does not get eaten
away) easily. The metal oxidizes readily above 660°C to form V2O5.
Vanadium is not found as a free metal in nature, but it is found as a
compound in many minerals, such as carnotite, roscoelite (a mica),
vanadinite, mottramite, and patronite. It is a white-to-gray metal, and is often
found as crystals. Pure vanadium has no smell. It usually combines with other
elements such as oxygen, sodium, sulfur, or chloride. Vanadium and
vanadium compounds can be found in the earth's crust and in rocks, some
iron ores, and crude petroleum deposits. It is also present in some crude oils.
Vanadium has been identified in the spectra of the sun and other stars.
Vanadium oxide is a yellow-orange powder, dark-gray flakes, or yellow
crystals.
