why is rubidium more reactive than sodium

Join now. [45][46] Such rubidium standards are often mass-produced for the telecommunication industry. [42], Rubidium has been used for polarizing 3He, producing volumes of magnetized 3He gas, with the nuclear spins aligned rather than random. [28][29], Rubidium is a minor component in lepidolite. Why don't libraries smell like bookstores? [48] Rubidium is also used as an ingredient in special types of glass, in the production of superoxide by burning in oxygen, in the study of potassium ion channels in biology, and as the vapor in atomic magnetometers. The now proven decay of 87Rb to stable 87Sr through beta decay was still under discussion in the late 1940s. One of the main uses is myocardial perfusion imaging. They presumed that it was a subchloride (Rb2Cl); however, the product was probably a colloidal mixture of the metal and rubidium chloride. Rubidium vapor is optically pumped by a laser, and the polarized Rb polarizes 3He through the hyperfine interaction. As with potassium (which is slightly less reactive) and caesium (which is slightly more reactive), this reaction is usually vigorous enough to ignite the hydrogen gas it produces. Kirchhoff and Bunsen processed 150 kg of a lepidolite containing only 0.24% rubidium monoxide (Rb2O). It turns red. [47], Other potential or current uses of rubidium include a working fluid in vapor turbines, as a getter in vacuum tubes, and as a photocell component. It is used as the main component of secondary frequency references (rubidium oscillators) in cell site transmitters and other electronic transmitting, networking, and test equipment. [49], Rubidium-82 is used for positron emission tomography. Is evaporated milk the same thing as condensed milk? [60] The biological half-life of rubidium in humans measures 31–46 days.

[52][53] Dialysis patients suffering from depression show a depletion in rubidium, and therefore a supplementation may help during depression. To ensure safety and purity, this metal is usually kept under dry mineral oil or sealed in glass ampoules in an inert atmosphere.
