More About Rubidium
What the name means: The word rubidium is derived from the Latin word rubidis, meaning deep red.
Who identified rubidium?: Rubidium was first identified in 1861 by Robert Wilhelm Bunsen and Gustav Robert Kirchhoff working in Germany. The two chemists were studying a mineral, from Saxony, called lepidolite. They used a spectroscope and discovered some new spectral emission lines that were deep red. The new element was named rubidium on account of its emission spectrum.
STP = standard temperature and pressure.
About rubidium: Rubidium is a Group 1 element. It is never found as a free element since it is far too reactive. Rubidium can be extracted from its compounds as a soft metal that will react spontaneously with oxygen in the air. It reacts violently with water, producing hydrogen gas as one of the products of the reaction.
