Silicon is a chemical element with symbol Si and atomic number 14. It is a tetravalent metalloid, more reactive than germanium, the metalloid directly below it in the table.Controversy about silicon's character dates to its discovery; it was first prepared and characterized in pure form in 1823.lthough most free silicon is used in the steel refining, aluminium-casting, and fine chemical industries (often to make fumed silica integrated circuits, the basis of most computers, a great deal of modern technology depends on it.
