Rubidium
 

Rubidium is a chemical element with symbol Rb and atomic number 37. Rubidium is a soft, silvery-white metallic element of the alkali metal group, with a standard atomic weight of 85.4678. Elemental rubidium is highly reactive, with properties similar to those of other alkali metals, including rapid oxidation in air. On Earth, natural rubidium comprises two isotopes: 72% is the stable isotope, 85Rb; 28% is the slightly radioactive 87Rb, with a half-life of 49 billion years—more than three times longer than the estimated age of the universe.

German chemists Robert Bunsen and Gustav Kirchhoff discovered rubidium in 1861 by the newly developed technique, flame spectroscopy.

Rubidium's compounds have various chemical and electronic applications. Rubidium metal is easily vaporized and has a convenient spectral absorption range, making it a frequent target for laser manipulation of atoms.

Rubidium is not a known nutrient for any living organisms. However, rubidium ions have the same charge as potassium ions, and are actively taken up and treated by animal cells in similar ways.

Rubitoutium ?

This is extremely dangerous to our democracy.

I miss Rainman!

What kind of soup?

Rubidium!!

The species lepidolite is largely used for the manufacture of lithium and rubidium salts.

Lithium, sodium, potassium, rubidium and caesium, and of the alkaline earth metals, viz.

idi

um.

Thanks you!

*pours one out for Simplex3*

If that element is #37 you call that Delaneyum or you kiss your closest friends,ale relatives with an open mouth.

Goes great with chicken.
