what is silicon

what is silicon Name Origin
Latin silex, or silicis (meaning what were more generally termed "the flints" or "hard rocks" during the Early Modern era where nowadays we would say "silica" or "silicates")
"Silicon" in different languages. Sources
Silicon is the second most abundant element and comprises 25.7% of the earth's crust (oxygen is first). Makes up major portion of clay, granite, feldspar, mica, asbestos, quartz (SiO2), and sand.
Primary producers are Austria, Italy, India, South Africa, Australia, Canada, the USA and Brazil.

Every year around 5000 tons of electronics grade silicon is produced.


Abundance
Universe: 700 ppm (by weight)
Sun: 900 ppm (by weight)
Carbonaceous meteorite: 1.4 x 105 ppm
Earth's Crust: 2.771 x 105 ppm
Seawater:
Atlantic surface: 0.03 ppm
Atlantic deep: 0.82 ppm
Pacific surface: 0.03 ppm
Pacific deep: 4.09 ppm
Human:
260000 ppb by weight
58000 ppb by atoms


Uses
Used in glass as silicon dioxide (SiO2). It is used as a semiconductor to make microchips for electronics (like your computer). Silicon is also used in solar cells, tools, cement, LCDs, grease and oils.


History
Silicon (Latin silex, silicis for flint, flint's) was first identified by Antoine Lavoisier in 1787, and was later mistaken by Humphry Davy in 1800 for a compound. In 1811 Gay-Lussac and Thenard probably prepared impure amorphous silicon through the heating of potassium with silicon tetrafluoride. In 1824, Berzelius prepared amorphous silicon using approximately
the same method as Lussac. Berzelius also purified the product by repeatedly washing it.
