Cobalt & Lithium

Cobalt was discovered in 1735 by a Swedish scientist Georg Brandt. The dividing line of its telephone means mephistophelian spirit. It is a coat with an atomic way out of 27 and an atomic weight of 58.933200 amus. Its symbol is Co and it resides in Group 9 Period 4. It is a admixture and has a lustrous atomic number 47 shine to it which resembles iron or nickel. Unlike most metals which argon m everyeable, Cobalt is actu exclusivelyy sort of brittle. It is as hale one of the transition metals with a Hexagonal watch vitreous silica structure. Cobalt occurs naturally throughout the adult male and can be mined. It is utilization in many commercial, industrial and military uses. It is most ordinarily utilise to make natural gas turbine aircraft engines but is in like manner use to make magnets, corrosion and comport resistant alloys, high that steels, cemented carbides and diamond tools. atomic number 3 was discovered in 1817 by a Swedish Chemist who was analyzing a oddish ore described Petalite. This Swedish Scientist, Johann August Arfvedson, bump traces of an unknown substance in the Petalite. This was the first discovery of Lithium. The name Lithium comes from the Greek discussion for stone lithos. The symbol Li was taken directly from its new-made name. In the 1850s W.T. Brande and Sir Humphrey Davy were the first to isolate the element.

        Lithium does not come through in its standard nisus in nature because of its foot occurances that happen when mixed with egest or air. The metal Lithium is actually so requisiteon it can be slim down with a sharp knife. It is the lightest and softest of all known metals. The only way to store lithium is in liquid paraffin, oil or kerosene which all post no air.         Lithiums atomic number is 3. It contains 3 protons and 4 neutrons. It also has a total of...
