About the Element Rubidium, the 37th element in the periodic table, was discovered by Robert Wilhem Bunsen and Gustav Robert Kirchhoff at the University of Heidelberg in 1861. It is a soft, silvery-white metallic element of the alkali metal group. It reacts violently with water and can ignite spontaneously in air. The element gives a reddish-violet color to a flame, hence its name. Rubidium salts are used in fireworks, glasses, and ceramics to give them a purple colour. The metal is also used in atomic clocks, in the manufacture of photocells and in the removal of residual gases from vacuum tubes. Rubidium is named after the Latin "rubidus" which means "deepest red."
