Silicon is a chemical element with the symbol Si and atomic number 14. It is a hard, brittle crystalline solid with a blue-grey metallic luster, and is a tetravalent 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. It is … Zobacz więcej Owing to the abundance of silicon in the Earth's crust, natural silicon-based materials have been used for thousands of years. Silicon rock crystals were familiar to various ancient civilizations, such as the predynastic Egyptians Zobacz więcej Silicon is the eighth most abundant element in the universe, coming after hydrogen, helium, carbon, nitrogen, oxygen, iron, … Zobacz więcej Compounds Most silicon is used industrially without being purified, and indeed, often with comparatively little processing from its natural form. … Zobacz więcej Physical and atomic A silicon atom has fourteen electrons. In the ground state, they are arranged in the electron … Zobacz więcej Crystalline bulk silicon is rather inert, but becomes more reactive at high temperatures. Like its neighbour aluminium, silicon forms a thin, continuous surface layer of Zobacz więcej Silicon of 96–99% purity is made by reducing quartzite or sand with highly pure coke. The reduction is carried out in an electric arc furnace, with an excess of SiO 2 used to stop Zobacz więcej Although silicon is readily available in the form of silicates, very few organisms use it directly. Diatoms, radiolaria, and siliceous sponges use biogenic silica as a structural material for … Zobacz więcej WitrynaSilicon is classified as a metalloid since some of its properties are similar to those of metals and some of its properties are similar to those of nonmetals.
