37 Rb Rubidium 85.4678 nuclear Number: 37 Atomic Weight: 85.4678 Melting define: 312.46 K (39.31°C or 102.76°F) Boiling Point: 961 K (688°C or 1270°F) assiduity: 1.53 grams per cubic centimeter Phase at Room Temperature: Solid Element classification: Metal Period Number: 5    Group Number: 1    Group Name: root word Metal Whats in a anatomy? From the Latin word for deepest ruby, rubidus. variety what? Rubidium is pronounced as roo-BID-i-em. History and Uses: Rubidium was honour by the German chemists Robert bunsen burner and Gustav Kirchoff in 1861 while analyzing samples of the mineral lepidolite (KLi2Al(Al, Si)3O10(F, OH)2) with a device called a spectroscope. The sample produced a typeset in of deep red spectral lines they had never seen before. bunsen burner was ultimately able to attach samples of rubidium metal. Today, most rubidium is obtained as a spin-off of refining lithium. Rubidium is utilize in vacuum tubes as a getter, a tangible that combines with and removes tip gases from vacuum tubes.
It is alike employ in the fictionalization of photocells and in special glasses. Since it is slowly ionized, it might be used as a propulsive in ion engines on spacecraft. new-made discoveries of commodious deposits of rubidium bespeak that its usefulness will development as its properties become fracture understood.
