What is the common name of rubidium?
Rubidium is the second most reactive metal and is very soft, with a silvery-white lustre. Rubidium was discovered (1861) spectroscopically by German scientists Robert Bunsen and Gustav Kirchhoff and named after the two prominent red lines of its spectrum….rubidium.

How was rubidium named?
The name derives from the Latin rubidus for “deepest red” because of the two deep red lines in its spectra. Rubidium was discovered in the mineral lepidolite by the German chemist Robert Wilhelm Bunsen and the German physicist Gustav-Robert Kirchoff in 1861.
How many isotopes of Rb are there?
two
Rubidium has two naturally occurring isotopes, 85Rb (72.2%) and 87Rb (27.8%). Rb is radioactive, with a half-life of 48.8 x 109 years. It readily substitutes for K in minerals, and is therefore fairly widespread.
What are 5 uses of rubidium?
According to the New World Encyclopedia, rubidium doesn’t have many commercial uses but it is used in vapor turbines, in vacuum tubes, in photocells, in atomic clocks, in some types of glass, the production of superoxide by burning oxygen, and with potassium ions in several biological uses.
