It is much more important to the metabolism of plants, particularly many grasses, and silicic acid (a type of silica) forms the basis of the striking array of protective shells of the microscopic diatoms. Computer Chips Silicon is a big part of what makes computers work. Silicon is an essential element in biology, although only tiny traces of it appear to be required by animals. The same way silicon is used to make glass, it is also used to make pottery. It is also a constituent of silicones, a class-name for various synthetic plastic substances made of silicon, oxygen, carbon and hydrogen, often confused with silicon itself. In the form of silica and silicates, silicon forms useful glasses, cements, and ceramics. Silicon is widely used in semiconductors because it remains a semiconductor at higher temperatures than the semiconductor germanium and because its native oxide is easily grown in a furnace and forms a better semiconductor/dielectric interface than any other material. It is the principal component of most semiconductor devices, most importantly integrated circuits or microchips. On Earth, silicon is the second most abundant element (after oxygen) in the crust, making up 25.7% of the crust by mass. Found in everything from spaceships to synthetic body parts, silicon can be found all around. Its stable tetrahedral configuration makes it incredibly versatile, and it is used in various ways in our everyday lives. As the eighth most common element in the universe by mass, silicon very rarely occurs as the pure free element in nature, but is more widely distributed in dusts, planetoids and planets as various forms of silicon dioxide (silica) or silicates. Silicon, the second most abundant element on earth, is an essential part of the mineral world. The concentration of the plant-available form of Si in soil solutions, monosilicic acid (H 4 SiO 4 ), varies between 0.1 and 0. A tetravalent metalloid, silicon is less reactive than its chemical analog carbon. Silicon (Si) is the second most abundant element (after oxygen) in the Earth’s crust, mainly occurring as various silicate minerals in most soils. It is a chemical element, which has the symbol Si and atomic number 14. Silicon (pronounced /ˈsɪlɨkən/ or /ˈsɪlɨkɒn/, Latin: silicium) is the most common metalloid.
