Silicon

Silicon is a chemical element with the symbol Si and atomic number 14. It is a hard, brittle crystalline solid with a blue-grey metallic luster. In its pure form, it is a semiconductor, which means it has conductivity between that of a conductor and an insulator. Silicon is the second most abundant element in the Earth's crust, making up about 27.7% of the crust by mass.
