Silicon (/ ˈsɪl.ɪ.kən /, SILL-ih-kən) [14] is a chemical element; it has symbol Si and atomic number 14. It is a hard, brittle crystalline solid with a blue-grey metallic lustre, and is a tetravalent non-metal (sometimes considered as a 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 ...
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.
Element Silicon (Si), Group 14, Atomic Number 14, p-block, Mass 28.085. Sources, facts, uses, scarcity (SRI), podcasts, alchemical symbols, videos and images.
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.
