Silicon is a chemical element; it has symbol Si and atomic number 14. It is a hard, brittle crystalline solid with a blue-grey metallic luster, and is a tetravalent metalloid and semiconductor. It is a member of group 14 in the periodic table: carbon is above it; and germanium, tin, lead, and flerovium are below it. It is relatively unreactive.
Silicon, a nonmetallic chemical element in the carbon family that makes up 27.7 percent of Earth’s crust; it is the second most abundant element in the crust, being surpassed only by oxygen. Learn more about the characteristics, distribution, and uses of silicon in this article.
Silicon, as silicate, is present in pottery, enamels and high-temperature ceramics. Silicon carbides are important abrasives and are also used in lasers. Biological role. Silicon is essential to plant life but its use in animal cells is uncertain. Phytoliths are tiny particles of silica that form within some plants.
