Phosphorus
atomic symbol, P, phosphorus is the 15th element in the periodic table (atomic number 15) with an atomic weight of 30.91. A group V element phosphorus is a donor in silicon, i.e., makes silicon N-type. Phosphorus a commonly used N-type dopant and has a relatively high diffusivity compared to arsenic and antimony, other common N-type dopants, and a diffusivity and similar to boron, the most common P-type dopant.

Phosphorus
(n.)
The morning star; Phosphor.
(n.)
Hence, any substance which shines in the dark like phosphorus, as certain phosphorescent bodies.
(n.)
A poisonous nonmetallic element of the nitrogen group, obtained as a white, or yellowish, translucent waxy substance, having a characteristic disagreeable smell. It is very active chemically, must be preserved under water, and unites with oxygen even at ordinary temperatures, giving a faint glow, -- whence its name. It always occurs compined, usually in phosphates, as in the mineral apatite, in bones, etc. It is used in the composition on the tips of friction matches, and for many other purposes. The molecule contains four atoms. Symbol P. Atomic weight 31.0.

Phosphorus
Second most abundant mineral in the body found in every living cell. Involved in the proper functioning of both muscles and nerves. Needed for metabolic processes of all cells, to activate many other nutrients. The phosphorus content of the body is approximately one percent of total body weight. Phosphorus combines with fats to form phospholipids. It takes part in the production of energy for the body, and it is second only to calcium as a constituent of bones and teeth. Phosphorus is necessary for metabolic functions relating to the brain and the nerves, as well as for muscle action and enzyme formation.

Phosphorus
An essential chemical food element that can contribute to the eutrophication of lakes and other water bodies. Increased phosphorus levels result from discharge of phosphorus-containing materials into surface waters.

Phosphorus
Phosphorus phosphoros (Greek) Light-bringing; equivalent of Latin Lucifer (the morning star; a torchbearer, e.g., Hecate, a form of the moon). Satan, according to Christian legend, was once Phosphorus, the redeemer. Also a personified aspect of the astral fire and light in the anima mundi. Eliphas Levi speaks of the interior phosphorus, meaning the astral light.
In alchemy and chemistry, applied to any substance which emitted light, but was monopolized for the familiar chemical element first isolated by Brandt of Hamburg in 1669.

Phosphorus is commonly misspelled "phosphorous". It is an essential component of living systems and is found in nervous tissue, bones and cell protoplasm. Phosphorus exists in several allotropic forms including white (or yellow), red, and black (or violet). White phosphorus has two modifications. Ordinary phosphorus is a waxy white solid. When pure, it is colourless and transparent. It is insoluble in water, but soluble in carbon disulphide. It catches fire spontaneously in air, burning to P4O10, often misnamed as phosphorus pentoxide. When exposed to sunlight, or when heated in its own vapour to 250°C, it is converted to the red variety. This form does not ignite spontaneously and it is a little less dangerous than white phosphorus. The red modification is fairly stable and sublimes with a vapour pressure of 1 atmosphere at 417°C.

Phosphorus
Phosphorus, (, meaning "light", and phoros meaning "bearer"), is the chemical element that has the symbol P and atomic number 15. A multivalent nonmetal of the nitrogen group, phosphorus is commonly found in inorganic phosphate rocks.
Due to its high reactivity, phosphorus is never found as a free element in nature. One form of phosphorus (white phosphorus) emits a faint glow upon exposure to oxygen (hence its Greek derivation and the Latin 'light-bearer', meaning the planet Venus as Hesperus or "Morning Star").
Phosphorus is a component of DNA and RNA and an essential element for all living cells. The most important commercial use of phosphorus-based chemicals is the production of fertilisers.
