37 Rb Rubidium 85.4678 Atomic morsel: 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 subprogram: 5    Group Number: 1    Group be: bag Metal Whats in a name? From the Latin word for deepest red, rubidus. grade what? Rubidium is pronounced as roo-BID-i-em. storey and Uses: Rubidium was detect by the German chemists Robert Bunsen and Gustav Kirchoff in 1861 while analyzing exemplars 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 religious 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 civilisation lithium. Rubidium is employ in vacuum tubes as a getter, a material that com bines with 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 usefulness will increase as its properties become better understood.
