Aluminium has 13 electrons and protons in orbit around its nucleus. Therefore Aluminium Atomic Number is “13” and Atomic Symbol is “Al.” This metal belongs to the boron group and is known for its strength and light weight. The metal is nonmagnetic and resists oxidation (rusting). Aluminium is difficult to ignite yet has a high energy density. Aluminium oxide was used as the primary fuel for the space shuttles’ solid rocket boosters. Aluminium reflects 92 percent of visible light as well as UV light. The powder form of Aluminium is a common ingredient in suntan lotion. Because it is highly conductive yet lightweight, Aluminium is used to produce a majority of the wiring electrical transmission networks.
It was discovered by a Danish scientist Hans Christian Oersted in 1825, however it is debatable because scientists were already aware of alum, an oxidized Aluminium, as early as 1787. Danish scientist, Hans Christian Oersted was the first to produce tiny amounts of pure Aluminium. In 1808, Humphry Davy together with other scientists identified a metal base of alum and alumina as its oxide, which Humphry Davy originally called “aluminum” but was later called Aluminium. There are several spelling differences with Aluminium, sometime it is also spelled as Aluminium.
It is remarkable for its light density and ability to resist corrosion due to the phenomenon of passivation. It is vital element for our modern industrial development especially aerospace industry, all major transportation. Our day to day uses most commonly known as Aluminium foil. In keeping with its pervasiveness, Aluminium is well tolerated by plants and animals.
