Beryllium

Beryllium is a highly toxic surface, and if exposed to it you can get a chronic beryllium disease. The way you ar exposed to the toxic metal is through inhalation pathways. The main(prenominal) effects of beryllium if exposed to it toxically are on the respiratory nerve pathway such as the lungs. If beryllium combines with a protein and goes into the coloured or spleen, it may result in a decelerate hypersensitivity immune response. Berylliums symbol is Be. Beryllium apply to be called Glucinium after the Greek battle cry glykys. This name means sweet, and is used because of Berylliums initial chit chat and observation. Berylliums nuclear number is 4 and its atomic weight is 9.01. Its pure metal form melts at 1278 degrees Celsius. Beryllium is an alkaline earth metal. It belongs to group II of the oscillate table and was discovered in 1798 by L.M. Vauquelin. He was a French chemist who was doing work with aluminum, and noticed a glossy powder that was nothing l ike aluminum. He named this substance atomic number 4 because of its sweet taste. In 1828 a German metallurgist trim it to a metal like organize and named it beryllium.

Beryllium has numerous properties such as a springy high stiffness, and a very low density. It has the strength of brand name without steels weight. It has an unusually high melting contingent and good galvanising conductive properties. Berylliums metal properties are very useful for electronic industries. In stopping point beryllium has a very controversial history. In the set about it starts as a harmless, white, sweet powder that we ca lled glucinium. As the eld went on it fals! e into a toxic metal that could continue your inhalation pathways called beryllium. all(prenominal) in all, beryllium is very important for or so pains uses, that causes little or no deadly ill effects to the workers.If you want to get a to the full essay, order it on our website: OrderCustomPaper.com
