Phosphorus is element 15 on the periodic table. It has two allotropes, red and white phosphorus. Phosphorus symbol is (P). Phosphorous is an element that is very essential to a majority forms of lifes. This element is the sixth abundant element in living organisms.(http://www.chemicool.com/). (P) is a nonmetal or a metalloid The name phosphorus come from the Greek word ‘phosphorus’ meaning bringer of light. (http://www.chemicool.com/) . (P) has an atomic number of fifteen. It does exist in nature in two forms white and red (P). Phosphorus is deadly if a dose of 50 mg is injected into the body. The melting point of phosphorus (white) is 44.1°C, boiling point (white) is 280°C (http://chemistry.about.com/) . This element has a white and waxy luster and color to it. It has no color to it at all. Phosphorus is a base thus it does not react with metals, feels a bit slippery, and has a bitter taste. There is not one specific type of phosphorus, but three types this includes black, white, and red phosphorous. White phosphorus is made is produced industrially. It is used as a filler as well as used in the military this element is very toxic and flammable substance. Red phosphorus is not at times red but orange and or purple. There are multiple uses for red phosphorus this includes the making of the strike plate of matchboxes, promoting plant growth in fertilizers, pesticides, drugs, fireworks, bombs, flares and in my opinion about anything that is commonly used in starting a fire. Black phosphorus is made not found. It is extracted from high pressure. This particular phosphorus does conduct electricity and has a almost graphite appearance to it. In nature (P) is not in a pure form, but rather as phosphates. Phosphates include minerals those that have have an appearance like rocks and in organic molecules.
Phosphorus is very critical to the human systems. Henning Brand extracted Phosphorus from patients urine, it was kept confidential into a Academy of Sciences took interest in such experiment.
Phosphorus has twenty three isotopes.
