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.
- Bismuth metal is soluble and reacts with concentrated nitric acid.
- It oxides are used as a yellow pigment in paint. Bismuth chloride oxide BiClO gives a pearly texture to cosmetics.

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.
- Tin and bismuth alloys have a very low melting point and hence it is used in fire detector and the fire extinguishers. It also used in electric solders and fuses.
