Chemistry - Aluminum
The metal with color silvery-white, soft, nonmagnetic, and ductile metal property, is known as aluminum.
The symbol of aluminum is ‘Al’ and its atomic number is ‘13.’
The Chemical element aluminum belongs to the boron group.
- Bauxite is the chief ore of the aluminum.
Salient Features of Aluminum
Aluminum metal is a chemically reactive element.
Aluminum has the potential to resist corrosion and the process of this resistivity is known as passivation.
Aluminum is a comparatively durable, lightweight, soft, malleable, and ductile, metal.
Aluminum is nonmagnetic and does not get ignite easily.
An aluminum film is a very good reflector of visible light, as it reflects more than 90 percent of incoming rays.
Aluminum commonly reacts with water and forms hydrogen.
Aluminum is the metal of low density and it has the property to resist corrosion.
Aluminum has the property of heat and electricity conductivity and hence, it is a good conductor.
Occurrence of Aluminum
Aluminum makes up (about) 8 percent of the Earth's crust.
After oxygen and silicon, aluminum is the third most abundant element; however, it is the most abundant metal in the crust.
When hydrogen fuses with magnesium, it creates stable aluminum.
Aluminum naturally found in oxides or silicates states.
Compounds of Aluminum
Following are the major compounds of aluminum −
Alumina - Al2O3
Aluminum chloride - AlCl3
Aluminum sulphate - Al2(SO4)3
Aluminum hydroxide - Al(OH)3
Aluminum carbide - Al4C3
Usage of Aluminum
Aluminum has wide range of usages in the industries as well as in everyday life; significant of them are −
Aluminum is used in transportation industries, such as railway, automobiles, aircraft, spacecraft, trucks, marine vessels, bicycles, etc.
