Top 13 interesting facts about Phosphorus

  • Phosphorus was discovered in 1669 by the German chemist Hennig Brand and its name derives from the Greek word "phos" which means "light" and "phoros" which means "bearer".
  • Phosphorus has the melting point at 44.1 °C (317.25 K, 111.38 °F) and the boiling point at 280.0 °C (553.15 K, 536.0 °F).
  • Phosphorus was the 13th discovered element and it was extracted from urine.
  • Phosphorus is a very reactive element so it can not be found as a free element on Earth.
  • Phosphorus is also called “the Devil’s element” because it is used in explosives and different poisons.
  • The term phosphorescence derives from the property of phosphorus to emit light when it is in contact with oxygen.
  • The vast majority of phosphorus compounds are used as fertilizers.
  • Phosphorus is also used in detergents, pesticides, and matches.
  • Phosphorus is a very important element for life and a major component of DNA.
  • Phosphorus has twenty-three isotopes but only one is stable, P-24.
  • Phosphorus can be found only in minerals, in compounds with other elements, mainly in phosphates.
  • About 50 percent of world reserves of phosphorus are in Arab countries.
  • There are two very common allotropic forms of phosphorus, white phosphorus and red phosphorus; red phosphorus is more stable and it is less dangerous. White phosphorus is extremely reactive; it burns instantly in air.
