Phosphorus Element in Periodic Table | Atomic Number Atomic Mass

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 12^th 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.
