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.
