What is Aluminum?
- Aluminium is a soft, silvery-white, ductile, nonmagnetic metal in the boron group. It is the third most abundant element in the Earth’s crust. Depending on the surface reference, aluminum appears in the range from silvery to dull gray.
Uses of Aluminum
- It is used in the transportation of railway, trucks, automobiles as castings.
- It is used in packaging.
- Al(II) compounds are observed in the reactions of Al metal with oxidants.
- Using aluminon the presence of aluminum can be detected in qualitative analysis.
Properties of Aluminum
- The element is highly reactive. It has about one-third of stiffness and density of steel.
- Aluminium has good corrosion resistivity.
- It is capable of superconductivity.
- They are many unknown isotopes of hydrogen with the mass number ranging from twenty-one to forty-one.
