What is Rubidium. Rubidium is a chemical element with atomic number 37 which means there are 37 protons and 37 electrons in the atomic structure. The chemical symbol for Rubidium is Rb. Rubidium is a soft, silvery-white metallic element of the alkali metal group, with an atomic mass of 85.4678. Elemental rubidium is highly reactive, with properties similar to those of other alkali metals, including rapid oxidation in air. Rubidium â Properties
Rubidium is used as a getter in vacuum tubes because it combines with and removes trace gases. It is also a component in photocells and has been used in making special glasses. Rubidium has been considered for use in ion engines in space shuttles, because it can be easily ionized.Cesium, however, is more efficient.t is a soft, silvery-white metallic element in the alkali group. [See Periodic Table of the Elements ]. Rubidium is the second-most electropositive and alkaline element. As with other alkali metals, it forms amalgams with mercury and alloys with gold, cesium, sodium and potassium.
