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 direction Temperature: Solid Element Classification: Metal Period rate: 5    Group Number: 1    Group tell apart: bag Metal Whats in a name? From the Latin word for deepest red, rubidus. grade what? Rubidium is pronounced as roo-BID-i-em. narration and Uses: Rubidium was detect by the German chemists Robert Bunsen and Gustav Kirchoff in 1861 while analyzing savours 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 atomic number 37 metal. Today, most rubidium is obtained as a byproduct of ameliorate lithium. Rubidium is utilize in vacuum tubes as a getter, a m aterial 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 superpower be used as a propellant in ion engines on spacecraft. Recent discoveries of commodious deposits of rubidium suggest that its service program will increase as its properties become better understood.
