37 Rb Rubidium 85.4678 Atomic flesh: 37 Atomic Weight: 85.4678 Melting lay: 312.46 K (39.31°C or 102.76°F) Boiling Point: 961 K (688°C or 1270°F) Density: 1.53 grams per cubic centimeter Phase at mode Temperature: Solid Element Classification: Metal Period recite: 5    Group Number: 1    Group construct: bag Metal Whats in a name? From the Latin word for deepest red, rubidus. grade what? Rubidium is pronounced as roo-BID-i-em. level and Uses: Rubidium was detect by the German chemists Robert Bunsen and Gustav Kirchoff in 1861 while analyzing savors of the mineral lepidolite (KLi2Al(Al, Si)3O10(F, OH)2) with a device called a spectroscope. The sample produced a put in of deep red unearthly lines they had never seen before. Bunsen was ultimately able to isolate samples of rubidium metal. Today, most rubidium is obtained as a byproduct of better lithium. Rubidium is apply in vacuum tubes as a getter, a material that combines wit h and removes tip gases from vacuum tubes.

It is also used in the manufacture of photocells and in special glasses. Since it is easily ionized, it power be used as a propellant in ion engines on spacecraft. Recent discoveries of commodious deposits of rubidium suggest that its good will increase as its properties become better understood.
