Interesting Facts
- Vanadium is a highly reactive metal, hence it is not found free in nature.
- Vanadium can be found in almost 65 different types of minerals.
  
- Zinc metal found (obtain) in many forms like granules, foil, dust and in a powder form.
- After iron, Zinc metal the second most abundant element in the earth crust.

Uses & Benefits
- Its ally with steel is used very tough and hence it is used in armor plates, axles, piston rods, tools and crankshafts.
-
Its oxide is used as pigments for glass and ceramics.
  
- It has corrosion resistance and hence it is used to plate other metals.
- Its alloys are very useful; Nichrome alloy is used in the hot coil of toasters and electric oven.
