Rubidium is a soft, silvery-white metal. It is one of the most electropositive alkali metals. It ignites spontaneously in air and reacts exothermically with water.

Applications of Rubidium and its Compounds:

Rubidium and its compounds have limited commercial applications. It is used in vacuum tubes as a getter to remove trace gases, and it is employed in the manufacture of photo-cells and specialised glass. It is also utilised in research; for example, Rubidium vapour is used to investigate atomic properties. In semiconductor manufacturing, Rubidium contributes to optimising electronic device performance. Given that Rubidium nitrate occasionally imparts a violet colour to pyrotechnic devices, its use extends to controlled applications in this field.
