Aluminum
The Romans used various aluminum compounds as astringents; they called them alum. The earliest Romans and Greeks used alum as an acerbic in dyeing. Sir Humphry Davy and other chemists in the early 19th century recognized aluminum in 1825, but Friedrich Wohler had more success and is usually credited with its first isolation, in 1827. H.E. Sainte-Claire Deville first prepared inexpensive pure metal in 1854 and set about perfecting a process for its commercial production. Yet, in 1886 the process by which aluminum is produced today was discovered independently by C.M. Hall, a student at Oberlin College, and Paul Heroult, a French metallurgist. Aluminum is a silvery-white metal with a face centered cubic crystalline structure. It is a member of group IIIa of the periodic table. The symbol is Al; atomic number is 13; atomic weight is 26.98154; it’s state at room temperature, 298 K, is a solid. The electron configuration is [Ne]. 3s2.3p1. The Shell structure for aluminum is: 2.8.3. Aluminum is ductile, malleable, as well as an excellent conductor of heat and electricity. The metal is soft but becomes stronger and harder when alloyed. It is the most abundant metal in the earth’s crust; 8% by weight,
Given that aluminum is lighter and less expensive than copper it is often utilized in high-tension power transmission. Aluminum is also used as a wrapping material to cover foodstuffs called Aluminum Foil. Aluminum in this form maintains the covered foods freshness as well as its desirable temperature of edibility. Aluminum is also mixed in paints as an aluminum powder. This is an important function of aluminum as paints are used in numerous amounts of structures across the country that aids in beautifying our environment. Aluminum powder is additionally mixed with iron oxide, called thermite, which is used in welding due to the large amount of heat expelled when the mix is ignited. Without the development of the welding technique, the structural quality of buildings would suffer drastically. Aluminum is commonly used as packaging for canned goods and drinks available at your local food stores. These are only five of the many ways aluminum is put to use on a day-to-day basis. Aluminum is a very important element not only for the periodic table but also for our everyday life. There are also many more uses than that of which I have listed. Aluminum includes numerous functions employed in every day life. Among the numerous applications of aluminum and its alloys, the major uses are in packaging (25% consumption; drinking cans and foil for pie plates and frozen foods), building and construction (15% siding and roofing, doors and windows), transportation (34% ; bodies, trim and mechanical parts of cars, boats, and planes), and electrical applications (8%; overhead transmission lines, cable sheathing, and wiring.) In the fourth and final section of this paper I’m going to tell you about six compounds formed from aluminu
