Rubidium
Rubidium is a soft, silvery-white metallic element of the alkali metal group, present in traces amounts in human tissues and fluids. Rb-87, a naturally occurring isotope, is (slightly) radioactive. Rubidium is very soft and highly reactive, with properties similar to other elements in group 1, like rapid oxidation in air. Rubidium, particularly 87Rb, in the form of vapor, is one of the most commonly-used atomic species employed for laser cooling and Bose-Einstein condensation. 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. Physiologically, it exists as an ion in the body. It has been found slightly increased in neoplastic human breast tissues obtained from patients at the time of mastectomy, compared to normal tissue. (PMID: 6488192, 15820728, 7324778, 9630429, 577330). Rubidium is a chemical element with the symbol Rb and atomic number 37. Rubidium is not known to be necessary for any living organisms. However, like caesium, rubidium ions are handled by living organisms in a manner similar to potassium ions, being actively taken up by plants and by animal cells. Rubidium, like sodium and potassium, almost always has ==+1== oxidation state when dissolved in water, including its presence in all biological systems. The human body tends to treat Rb==+== ions as if they were potassium ions, and therefore concentrates rubidium in the bodys intracellular fluid. The ions are not particularly toxic. [Wikipedia]. Rubidium is found in many foods, some of which are garden tomato, sweet orange, black walnut, and coconut.
