Electronic configuration Phosphorus is a chemical element of the periodic table of elements that has atomic number 15 and as the symbol P. It is a non-metal of the nitrogen group. At room temperature it is solid, but above 44.15 ° C immediately becomes liquid. Phosphorus is not found in nature in the elemental state, but in the form of phosphate (salt of phosphoric acid), it is abundant in some rocks and living cells of cells whose metabolism is an essential component. Elemental phosphorus is extremely reactive and, by combining with oxygen, it emits a slight luminescence (hence its name, φωσφορος, that is, phosphoros, which in Greek means "carrier of light"). The main industrial use of phosphorus is in the production of fertilizers. It is also used in the production of explosives, matches, artificial fire, pesticides, toothpastes, detergents and white leds. Phosphorus appears as a white waxy solid with its characteristic unpleasant agliaceous odor; When it is very pure it is transparent. It is insoluble in water and soluble in organic solvents, such as carbon disulfide. At contact with the air it burns spontaneously forming P2O5 diphosphorus pentoxide. #P #P15 #Phosphorus
