The atomic weight of rubidium

WebAtomic number of rubidium, atomic weight and charge. The rubidium atom donates an electron of the last shell to form bonds and turns into a rubidium ion(Rb +). That is, rubidium is a cation element. Rubidium was discovered in 1861 by Robert Bunsen and Gustav Kirchhoff, in Heidelberg, Germany, in the mineral lepidolite through flame spectroscopy. Because of the bright red lines in its emission spectrum, they chose a name derived from the Latin word rubidus, meaning "deep red". Rubidium is a minor component in lepidolite. Kirchhoff and Bunsen processed …
