Elemental rubidium is highly reactive, with properties similar to those of other alkali metals, such as very rapid oxidation in air. [43] Such spin-polarized 3He cells are useful for neutron polarization measurements and for producing polarized neutron beams for other purposes. The company's filing status is listed as Sos/Ftb Suspended/Forfeited and its File Number is 200036110050. Rubidium was discovered (1861) spectroscopically by German scientists Robert Bunsen and Gustav Kirchhoff and named This metal was discovered in 1861 by German chemists. 85Rb. The metal is a lithophile metallic element that … 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. Rubidium is very similar to potassium, and tissue with high potassium content will also accumulate the radioactive rubidium. Rubidium (Rb), a chemical element of Group 1 (Ia) in the periodic table, an alkali metal group. Rubidium Chloride (RbCl) Rubidium Floride (RbF) Rubidium Sulfate (Rb 2 SO 4) Interesting facts: It is the 16th most common element in the earth's crust. The chemical symbol for rubidium is Rb. The melting point of rubidium is 312.46 degrees Kelvin or 40.31 degrees Celsius or degrees Celsius. [27] Today the largest producers of caesium, such as the Tanco Mine, Manitoba, Canada, produce rubidium as a by-product from pollucite. Group Name: Alkali … Rubidium is a very soft, silvery-white metal in the alkali metal group. Rubidium. Rubidium (Rb) has an atomic number of thirty-seven. Its name comes from the Latin word rubidus, meaning deep red, the colour of its emission spectrum. The element was named after its characteristic red spectrum lines (from the Latin ‘rubidus’, dark red). Rubidium metal shares similarities to potassium metal and caesium metal in physical appearance, softness and conductivity. As a result of changes in the blood–brain barrier in brain tumors, rubidium collects more in brain tumors than normal brain tissue, allowing the use of radioisotope rubidium-82 in nuclear medicine to locate and image brain tumors. Kirchhoff and Bunsen processed 150 kg of a lepidolite containing only 0.24% rubidium monoxide (Rb2O). Rubidium is the chemical element with the symbol Rb and atomic number 37. Pronunciation: Roo-bid-ee-am Appearance: Grey white Mass Number: 85 Standard Atomic weight: 85.467 g/mol Atomic number (Z): 37 Electrons: 37 Protons: 37 Neutrons: 48 Period: 5 Group: 1 Block: s Element category: Alkali metal Electrons per shell: K2, L8, M18, N8, O1 Electron configuration: 1s22s22p63s23p63d104s24p65s1 Rubidium is one of the rarest and expensive metals in the world. It was discovered by the German physicist Gustav Kirchhoff and the chemist Robert Bunsen in 1861. Rubidium is an abundant element and is ranked as the twenty-third most abundant element in the Earth’s crust . Atomic Number of Rubidium: 37 Atomic Mass of Rubidium: 85.4678 Uses of Rubidium: Used as a catalyst, photocells, and vacuum and cathode-ray tubes. Rubidium forms peroxides on exposure even to a small amount of air diffused into the oil, and storage is subject to similar precautions as the storage of metallic potassium. Rubidium, particularly vaporized 87Rb, is one of the most commonly used atomic species employed for laser cooling and Bose–Einstein condensation. Rubidium. The atomic number of rubidium is 37. Melting Point: 312.46 K (39.31°C or 102.76°F) Boiling Point: 961 K (688°C or 1270°F) Density: 1.53 grams per cubic centimeter. [45][46] Such rubidium standards are often mass-produced for the telecommunication industry. This soft, silvery-white member of the alkalai metals group has thirty-seven protons in the nucleus of one atom. Au B. Aut C. Sn. How Many Electrons And Protons Are Contained In Each Cation? [49], Rubidium-82 is used for positron emission tomography. [35] Since then, the most important use of rubidium is research and development, primarily in chemical and electronic applications. [49] In particular, 87Rb is used with other alkali metals in the development of spin-exchange relaxation-free (SERF) magnetometers. The commercial production of rubidium is carried out from lepidolite, which contains up to 3.5% of rubidium . However there is a lot of funny facts about Rubidium that most … From the Latin word rubidus,deepest red. [52][53] Dialysis patients suffering from depression show a depletion in rubidium, and therefore a supplementation may help during depression. 12H2O yields after 30 subsequent steps pure rubidium alum.
