Silicon is located on the third period and the fourteenth group in the periodic table of elements. It is a Bluish-Black metallic solid with a melting point of 1,414 degrees Celsius. Silicon is a member of the metalloids . It can form up to 4 bonds. Silicon was identified in 1824 by Jons Jacob Berzelius as a powder. Finally in 1854, Henri Deville managed to produce crystalline Silicon. It makes a useful semiconductor, and is one of the most common elements in Earth's crust. You find most of it in the form of sand or clay which are Silicon dioxide, and Aluminium silicate. 

Silicon is an abundant element on Earth, making up about 28% of our crust. Its compounds have been used historically as early weapons in the form of flint, building materials such as granite, cement & concrete in the form of sand & clay, and many more. Today, Silicon is used in manufacturing computer chips.
