They found it in the mineral lepidolite by using a spectroscope. Properties of rubidium. At room temperature, rubidium can be a liquid. It 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.ubidium 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.
