Tarihi
German chemists Robert Bunsen and Gustav Kirchhoff discovered rubidium in 1861 by the newly developed method of flame spectroscopy.
The separation of the metal was tried by Bunsen, but he never got samples with more than 18% of Rubidium.
The separation of the metal was only accomplished by George de Hevesy, through the hydrolysis of melted rubidium hydroxide.
