3 Uses

3.1 Uses & Benefits

Plutonium was used in atomic bombs and still it is being used in various weapons and Ammunition industry.
It is also used in nuclear power plant as source of energy for space missions.

Uses of Scandium are limited to research purpose only. However, it has very low density and higher melting point.
Its compounds like scandium iodide is used in mercury vapor lamps to produce very bright white light.
