What is phosphorus?
phosphorus is a chemical element in the nitrogen group identified by the P -symbol on the periodic table of elements. The non -metallic element is extremely reactive and also highly toxic, although it is also an important trace mineral in most living organisms. There are a number of uses for phosphorus compounds, and most people interact with an element every day. When someone hits a match, a fertilizer or uses most of the electronics, this element is involved. Brandt noted that his discovery had a curious property shining when he was exposed, and he named him after the Greek phosphoros , which means "evening star". The atomic number of phosphorus is 15, placed it between lighter chemical elements and rarely, if it sometimes occurs in pure form.
As other elements in the nitrogen group, the peculiarity of phosphorus thstrurture causes very strong bonds with other elements. In addition to being highly reactive, it also ensures that it appears in many compounds. One of the most important groups of fosch compoundsForum is phosphates. There are many examples of phosphates; Most people are probably familiar with calcium phosphate, a mineral that consists of a majority of bone structure.
together with several other elements show phosphorus allotropy, which means that its pure form can occur in many ways in the same state. Carbon is another element that appears in radically different but still pure forms of diamond and coal. Phosphorus has three allotrops; White, red and black. White is the most toxic and reactive of three and appears as a wax solid that moves in color from white to yellow.
When exposed to air, white phosphorus will burn and the element also shines in the dark. The exposure to the heat or light is transformed by red phosphorus, which is a much more stable allotrop, which is used to make things like matches. If white phosphorus is heated under pressure, it turns into black phosphorus. AllY these forms are clean, but they look and behave very differently.
In addition to matches, phosphorus is also used in incendiary devices, fertilizers and fireworks. Some products can do sports on an anti -corrosive coating made of phosphorus and the element is also used as a Dopant in the production of electronics. Because the element is toxic, pure forms should be processed carefully, as well as many of its compounds.
