Phosphorus does not metallic chemical element symbol P

Phosphorus does not metallic chemical element symbol P
There is in every living cell, and has numerous manufacturing uses. In nature there are

only phosphorus in combinations called phosphate.
And phosphorus is essential to the life of plants, animals and natural growth. Plants soak up phosphorus from the soil, and use it in photosynthesis. People, animals and phosphorus gets to eat the plants, and the types of foods such as meat, milk, and eggs. There are about four-fifths of the human body phosphorus in bones and teeth. Phosphorus, an important part of ATP.

It is the main sources of phosphorus in the industrial use of rock phosphate called phosphorite. Phosphate rock and there are abundant in China and Morocco, and the United States. The Manufacturers manufactures two types of phosphorus from phosphate rock, are white phosphorus and red phosphorus, the chemical forms are called allotropes of phosphorus. Multiple chemical form.

White phosphorus solid waxy substance. In order to be prepared, produces Manufacturers First phosphorus vapor by heating the rock phosphate in the presence of coke and sand. And then the steam condenses to white phosphorus. And unite white phosphorus easily with other elements. It is also, automatically it ignites in air at about room temperature. For this reason, the white phosphorous is very toxic, and can cause serious burns when touched. And phosphorus also flash phosphorous, which radiates in the dark when exposed to air. Manufacturers use of white phosphorus in the manufacture of products such as steel, plastics, pesticides, fertilizers, drugs, animal feed, and water hardness removers and detergents. And detergents made from white phosphorus rich in phosphates, but phosphate detergents can seep into the lakes, and rivers through the discharge pipe, and contributes to the pollution of lakes and rivers that lead to fish and other marine organisms death. Pollution of lakes and rivers.


Red phosphorus and red brown powder, produced by heating white phosphorus, or Ptareidah to sunlight. Aeshetal and red phosphorus, or combine easily with other elements such as white phosphorus, is used in the manufacture of matches and safe, and in pesticides flies.
There is another chemical form of phosphorus, phosphorus is similar to so-called black granite, and can be accessed by heating white phosphorus under very high pressure. Black phosphorus and unite with other elements less than what happens in the cases of white phosphorus and red easily.
The atomic number of phosphorus-15, and atomic weight 30.97376. White phosphorus and melts at a temperature of 44.1 ° heat and boil at a temperature of 280 °. German chemist Hennig Brand phosphorus was discovered in 1669 AD.
