Uses
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.
