The primary difficulty associated with the production of pure rubidium is that it is always found together with cesium in nature and is also mixed with other alkali metals. Rubidium easily loses its single valence electron but no others, accounting for its oxidation number of +1, although several compounds that contain the anion, Rb-, have been synthesized. The alkali metals, lithium, sodium, potassium, rubidium and caesium all possess NMR active nuclei, all of which are quadrupolar. Sodium and potassium are the sixth and seventh most abundant of…, …is silver in tone, and rubidium, which is gold-toned.
