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.
- Currently known uses of Copernicium metal are limited to research purpose only.
