- Louis Nicolas Vauquelin discovered beryllium in the oxide form in both beryl and emeralds in 1798. Beryllium is a gray-white metal. From the Greek word beryllos, beryl; also called glucinium or glucinum, Greek glykys, sweet. Discovered in the oxide form by Vauquelin in both beryl and emeralds in 1798. The metal was isolated in 1828 by Wohler and by Bussy independently by the action of potassium on beryllium chloride.

Beryllium: the essentials Beryllium: the essentials. Beryllium is a Group 2 (IIA) element. It is a metal and has a high melting point. At ordinary temperatures, beryllium resists oxidation in air. Beryllium compounds are very toxic. Its ability to scratch glass is probably due to the formation of a thin layer of the oxide. Aquamarine and emerald are precious forms of the mineral beryl, [Be3Al2(SiO3)6].

Wikijunior:The Elements/Beryllium Because it also does not spark, it is used in non-sparking tools. Because it reacts with the alpha particles released by polonium to produce neutrons, it is used in A-bomb initiators. And finally, because it does not react with acid and uranium it is used to make nuclear generators.

Beryllium Because of its low density and atomic mass, beryllium is relatively transparent to X-rays and other forms of ionizing radiation; therefore, it is the most common window material for X-ray equipment and components of particle physics experiments.eryllium is a steel gray and hard metal that is brittle at room temperature and has a close-packed hexagonal crystal structure. It has exceptional stiffness (Young's modulus 287 GPa) and a reasonably high melting point. The modulus of elasticity of beryllium is approximately 50% greater than that of steel.

Berkelium Berkelium is a soft, silvery-white, radioactive actinide metal. In the periodic table, it is located to the right of the actinide curium, to the left of the actinide californium and below the lanthanide terbium with which it shares many similarities in physical and chemical properties.n Earth, berkelium is mostly concentrated in certain areas, which were used for the atmospheric nuclear weapons tests between 1945 and 1980, as well as at the sites of nuclear incidents, such as the Chernobyl disaster, Three Mile Island accident and 1968 Thule Air Base B-52 crash.

Ban beryllium in dentistry In dentistry, beryllium is used in a nickel alloy as a cheaper alternative to precious metals. The nickel alloy typically contains 1% - 2% beryllium. Although the beryllium composition is low, the risk to dental health professionals who grind, machine or polish the alloy is grave. Thousands of dental laboratory employees, primarily technicians, are being exposed to beryllium dust and fumes.
