Silicon

 Silicon was discovered by Jöns Jacob Berzelius, a Swedish chemist, in 1824 by heating chips of potassium in a silica container and then carefully washing away the residual by-products. Silicon is the seventh most abundant element in the universe and the second most abundant element in the earth's crust. Today, silicon is produced by heating sand (SiO2) with carbon to temperatures approaching 2200°C. Info found athttp://en.wikipedia.org/wiki/Silicon Silicon-

Silicon is a naturally occurring element in the earth’s crust. Its conductivity properties make it an **ideal semiconducting material**, and it is the primary material used in semiconductor wafers up to 300 mm in diameter.

Health hazardsNot a big health hazard as long as it is not ingested or put on open wounds. Production and use of products made by this element are not very hazardious to humans nor the enviroment.
