Top 14 interesting facts about Silicon

  • Silicon was discovered in 1823 by Jons Berzelius.
  • It takes its name from the Latin word "silex" which means "flint".
  • Its melting point is at 1410.0 °C (1683.15 K, 2570.0 °F) and boiling point at 2355.0 °C (2628.15 K, 4271.0 °F).
  • Silicon is the eight most common element in the universe by mass.
  • Silicon is the second most abundant element in the Earth crust by mass (28%) after Oxygen.
  • Silicon is hardly ever found as a pure element but in compounds (it is widely spread in dust and sand, and different forms of silicates).
  • Silicon is widely use in industrial building without being separated from its compounds.
  • Bricks, cement, mortar, and concrete are few of the usage of silicon in building industry.
  • Silicon is of a huge importance in porcelain and glass industries.
  • Elemental silicon (high purified silicon) is essential component of computers integrated circuits and high-technology devices.
  • Plants use silicon in their metabolism.
  • Silicon's density when liquid is greater than its density when solid.
  • Silicon forms compounds with many other elements or compounds.
  • Silicon has three stable isotopes Si-28 (the most common), Si-29, and Si-30.
