Silicon is a chemical element with symbol Si and atomic number 14. A hard and brittle crystalline solid with a blue-gray metallic luster, it is a tetravalent metalloid. Silicon was discovered by Jöns Jacob Berzelius, a Swedish chemist, in 18by 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. Silicon is element on the periodic table. Silicon looks like a metal, but does not do everything a metal does, like conduct electricity very easily.
