3 Uses

3.1 Uses & Benefits

Rubidium's main application is in the glass manufacturing.
Rubidium can very easily get ionized and hence it is used for ion engines, but it is still less efficient than that of Caesium.

It is use for coinage and bullion.
Most of copper element is used in manufacturing electrical and electronic equipments such as wirings and components. It is also used in construction and industrial machine.
