37 Rb Rubidium 85.4678 Atomic telephone number: 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 dwell Temperature: Solid Element Classification: Metal Period account: 5    Group Number: 1    Group come to: bag Metal Whats in a name? From the Latin word for deepest red, rubidus. grade what? Rubidium is pronounced as roo-BID-i-em. archives and Uses: Rubidium was detect by the German chemists Robert Bunsen and Gustav Kirchoff in 1861 while analyzing attempts 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 nuance lithium. Rubidium is apply in vacuum tubes as a getter, a material t hat combines 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 benefit will increase as its properties become better understood.
