Facts about Rubidium tell the readers about the chemical element with the atomic number 37. It is symbolized as Rb. The standard atomic weight of Rubidium is 85.4678. It is included in the alkali metal group. Rubidium is characterized in silver white color with soft texture. This metallic element is reactive. When it is exposed to air, it will have a rapid oxidation. The 85Rb is considered as the stable isotope of Rubidium. The element actually has two natural isotopes. The stable one comprises 72 percent. The 87Rb occupies the remaining 28 percent. Here are other interesting facts about Rubidium in the following post:
Facts about Rubidium 1: the discovery of Rubidium
In 1861, Rubidium was discovered by Robert Bunsen and Gustav Kirchhoff. Both were the famous chemists from Germany. Both applied flame spectroscopy to discover the element.
Facts about Rubidium 2: applications
The applications of Rubidium compounds are centered on electronics and chemistry. When the scientists want to apply the laser manipulation of atoms, they will use Rubidium as the target. The spectral absorption range and vaporization level of Rubidium is good.
