[19][26], For several years in the 1950s and 1960s, a by-product of potassium production called Alkarb was a main source for rubidium. [45][46] Such rubidium standards are often mass-produced for the telecommunication industry. It is a chemical element with the symbol ‘Rb’ and classified as alkali earth metal (group 1) in the periodic table. One of the main uses is myocardial perfusion imaging. We also provide  Rubidium Salts with other purities and particle sizes upon request. [19], Rubidium was discovered in 1861 by Robert Bunsen and Gustav Kirchhoff, in Heidelberg, Germany, in the mineral lepidolite through flame spectroscopy.

Technical data for Rubidium Click any property name to see plots of that property for all the elements. [59] The ions are not particularly toxic; a 70 kg person contains on average 0.36 g of rubidium, and an increase in this value by 50 to 100 times did not show negative effects in test persons. Its name comes from the Latin word rubidus, meaning deep red, the colour of its emission spectrum. It has 32 isotopes, 2 of them are naturally occurring. Please contact us for availability and quote. Its desirable features for this application include the ready availability of inexpensive diode laser light at the relevant wavelength and the moderate temperatures required to obtain substantial vapor pressures. Rubidium is used as a photocell component. It is one of the most electropositive and alkaline elements. The now proven decay of 87Rb to stable 87Sr through beta decay was still under discussion in the late 1940s. To ensure safety and purity, this metal is usually kept under dry mineral oil or sealed in glass ampoules in an inert atmosphere. Rubidium (Rb) has an atomic number of thirty-seven.

From the Latin word rubidus,deepest red. Illustration 1: What is the correct set of four quantum numbers for the valence electron of rubidium (Z = 37)? Wikipedia - Basics on Rubidium Atomic Number: 37. Although the distilled rubidium was pyrophoric, they were able to determine the density and the melting point. Au B. Aut C. Sn. [42], Rubidium has been used for polarizing 3He, producing volumes of magnetized 3He gas, with the nuclear spins aligned rather than random. Atomic Number: 37 Period Number: 5 Group Number: 1. Rubidium is the chemical element with the symbol Rb and atomic number 37. [28][29] Rubidium was the second element, shortly after caesium, to be discovered by spectroscopy, just one year after the invention of the spectroscope by Bunsen and Kirchhoff. Rubidium is the chemical element with the symbol Rb and atomic number 37. Atomic Number: 37      Period Number: 5       Group Number:  1. Rubidium is one of the rarest and expensive metals in the world. The melting point of rubidium is 312.46 degrees Kelvin or 40.31 degrees Celsius or degrees Celsius.
