What does silicon mean?

Noun Plural: silicons
silicon - a tetravalent nonmetallic element; next to oxygen it is the most abundant element in the earth's crust; occurs in clay and feldspar and granite and quartz and sand; used as a semiconductor in transistors
		Si, atomic number 14
		chemical element, element the most favorable environment for a plant or animal; "water is the element of fishes"
		semiconducting material, semiconductor a substance as germanium or silicon whose electrical conductivity is intermediate between that of a metal and an insulator; its conductivity increases with temperature and in the presence of impurities
		silicone, silicone polymer any of a large class of siloxanes that are unusually stable over a wide range of temperatures; used in lubricants and adhesives and coatings and synthetic rubber and electrical insulation
		clay United States politician responsible for the Missouri Compromise between free and slave states (1777-1852)
		feldspar, felspar any of a group of hard crystalline minerals that consist of aluminum silicates of potassium or sodium or calcium or barium
		granite something having the quality of granite (unyielding firmness); "a man of granite"
		quartz a hard glossy mineral consisting of silicon dioxide in crystal form; present in most rocks (especially sandstone and granite); yellow sand is quartz with iron oxide impurities

silicon (Noun)
A nonmetallic element symbol Si with an atomic number of 14 and atomic weight of 28. 0855.

silicon (n.)
A nonmetalic element analogous to carbon. It always occurs combined in nature, and is artificially obtained in the free state, usually as a dark brown amorphous powder, or as a dark crystalline substance with a meetallic luster. Its oxide is silica, or common quartz, and in this form, or as silicates, it is, next to oxygen, the most abundant element of the earth's crust. Silicon is characteristically the element of the mineral kingdom, as carbon is of the organic world. Symbol Si. Atomic weight 28. Called also silicium.

silicon
A brittle metalloid element with symbol Si and atomic number 14 that exists in two allotropic forms; occurs principally in sand, quartz, granite, feldspar, and clay. It is usually a grey crystalline solid but is also found as a brown amorphous powder. It is used in transistors, rectifiers, solar cells, and alloys. Its compounds are widely used in glass manufacture, the building industry, and in the form of silicones.

Silicon is element 14 on the periodic table. Its symbol is Si.

Silicon looks like a metal, but does not do everything a metal does, like conduct electricity very easily. It is a metalloid. Silicon is used a great deal in today's computers.

There is a lot of silicon on the Earth. At the beach, there is silicon in the form of sand. Sand is a compound of silicon known as silicon dioxide or silica. Glass is made by heating sand (or silicon dioxide) hot enough. The glass can have different colors by adding colored compounds. Silicon also makes up a lot of different rocks and minerals, and they are known as silicates.
