Abstract. Rubidium (Rb) from the Latin word "rubidus" (darkest red) was discovered by Bunsen and Kirchoff in 1861. It is one of the Group IA alkali metals. This is the same periodic series to which lithium, sodium, potassium, francium, and cesium belong. Rubidium, like potassium, is concentrated intracellularly by most living tissue.

Twenty four isotopes of rubidium are known. Naturally occurring rubidium is made of two isotopes, 85 Rb and 87 Rb. Rubidium-87 is present to the extent of 27.85% in natural rubidium and is a beta emitter with a half-life of 4.9 x 10 10 years. Ordinary rubidium is sufficiently radioactive to expose a photographic film in about 30 to 60 days.
