✅ Aluminum

✍️Introduction
➖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
➖Alumina - Al2O3
➖Aluminum chloride - AlCl3
➖Aluminum sulphate - Al2(SO4)3
➖Aluminum hydroxide - Al(OH)3
➖Aluminum carbide - Al4C3

✍️Usage of Aluminum
➖Aluminum is used in transportation industries, such as railway, automobiles, aircraft, spacecraft, trucks, marine vessels, bicycles, etc.
➖Aluminum is used in packaging some specific materials.
➖Aluminum is used in the constructions of doors, windows, building wire, sheathing, roofing, etc.
➖Aluminum is largely used in making electric wire.
➖Aluminum is used in making home appliances and many other household items, such as cooking utensils.
➖Aluminum is used in baseball bats, watches, and many more such kind of stuffs.
➖Aluminum is used in photographic equipment.
➖Aluminum is used in electronic appliances.
➖Aluminum is used as light reflector, as it is a good light reflector; basically, some of the materials are aluminum coated specially to reflect light.
➖Aluminum is used in production of hydrogen gas by reaction with hydrochloric acid.
➖Aluminum is used in manufacturing musical instruments.
