Silicon

Silicon Silicon the most common used per caster on ball was discovered I 1824, by Jons Jacob Berzelius, a Swedish chemist. Berzelius discovered this element by heating chips of cat valium in a silica container and then care sufficienty slipstream away the relaxation by-products. The atomic number is 14, atomic weight: 28.086, melting flow: 1687K (1414°C) or 2577°F), boiling point: 3538k (3265°C or 5909°F), dumbness: 2.3296 grams per cubic centimeter, and the phase at agency temperature is solid. Silicon gets its name from the Latin word silex. The symbol for ti is Si. Silicon tolerate be found in aggroup 14 (or IV) of the hebdomadal table. Silicon is prepared by a brown amorphous mill or as a gray-black crystal. Silicon is made by heating silica, or te dioxide (SiO2), with reducing agent, such as carbon or magnesium, in an electric furnace. Silicon dissolves in sodium hydroxide, forming sodium silicate and atomic number 1 gas. At ordinary temperatures ti is impervious to air, only when spirited temperatures it reacts with oxygen, forming a layer of silica that does not react further. At high temperatures it also reacts with atomic number 7 and centilitre to form silicon nitride and silicon chloride, respectively. Silicon constitutes around 28 percent of the earths crust. It does not occur in the free, element state, but is found in the form of silicon dioxide and in the form of complex silicates.

Silicon containing minerals constitute nearly 40 percent of all common minerals, including more than 90 percent of igneous-rock-forming minerals. The mineral qu artz, varieties are the naturally occurring ! crystal forms of silica. Two allotropes of silicon aspirate round at room temperature: amorphous and vaporous. Amorphous appears as a brown powder white crystalline silicon that has a metallic luster and a grayish color. mavin crystals of crystalline silicon can be grown with a accomplish known as the...
