Phosphorus

Phosphorous Element:

Phosphorous Element- Phosphorus is a non-metallic chemical element and it is a member of group 15 and period 3 in the periodic table. Atomic number of Phosphorus is 15 and it is indicated by the symbol is P. P belongs to the nitrogen family. Arsenic, Antimony, Bismuth and Moscovium are the other elements in the nitrogen family. It  is the 12th most abundant element in Earth’s crust. White phosphorous, red phosphorus and black phosphorus are three allotropes of phosphorous. These allotropes all have different physical and chemical properties.31P is the stable isotope of phosphorus.

Uses of Phosphorous Element:

  • It  is used in steel manufacture and in the production of phosphor bronze.
  • It is also used to make LEDs
  • Red phosphorus is used in the manufacture of safety matches.
  • Phosphates are also used as ingredients in some detergents and in the production of special glasses and fine chinaware.
