Molybdenum :: Chemistry Essay

bit is a transition metal. It is representedby the symbol Mo. It is a pure metal that is issilverish white in color and real hard, and has one ofthe highest melting headers of all pure elements at4753 F. Its boiling point is 8382 F. Its density is10280 kg/m3 and its hardness is 5.5. It has a molarvolume of 9.38 10-6 m3/mol. bit has an atomic weight of 95.94 amu. Itsatomic number is 42. The atomic radius is one hundred forty-five pm andthe covalent radius is 145 pm also. Its electron shape is Kr4d5 5s1. It is a strong acid.Its crystal structure is body center cubic.Over 2/3 of all molybdenum is used in alloys. molybdenum use increased a lot during World struggle I,when demand for tungsten made tungsten rare, andstrong steels were at expensive. bit is used inaircraft and missile parts, and in filaments.Molybdenum acts as a catalyst in the petroleumindustry for removing organic sulfurs from petroleumproducts.Molybdenum is not found in nature, and the compoundsthat can be found we re, until the previous(a) 1700s confusedwith other elements, such as carbon and lead. In 1778Carl Wilhelm Scheele spy that molybdenum wasseparate from graphite and lead, and was able toisolate the oxide of the metal from molybdenite.Molybdenum was rarely used and stayed in thelaboratory until the late 19th century.Plants and animals for the most part have molybdenum, presentin very small amounts.
