Rubidium Element

37 Rb Rubidium 85.4678 Atomic total: 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 board Temperature: Solid Element Classification: Metal Period bout: 5    Group Number: 1    Group progress 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. tale and Uses: Rubidium was detect by the German chemists Robert Bunsen and Gustav Kirchoff in 1861 while analyzing try outs 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 apparitional 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 refining lithium. Rubidium is use in vacuum tubes as a getter, a material that 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 talent be used as a propellant in ion engines on spacecraft. Recent discoveries of commodious deposits of rubidium suggest that its emolument will increase as its properties become better understood.
