SiliconSilicon

Silicon is the chemical element with atomic number 14 and chemical symbol Si. Like carbon, it is tetravalent (it has 4 valence electrons), but it is less reactive than carbon. Silicon is the 2nd most abundant element in the Earth's crust, and most of that silicon is found in the form of silicate minerals. Silicon is a metalloid, and very highly purified silicon is used in semiconductor electronics.
