Phosphorus is a chemical element with the symbol P and the atomic number 15. Elemental phosphorus exists in two major forms, white phosphorus and red phosphorus, but because it is highly reactive, phosphorus is never found as a free element on Earth. It has an occurence in the Earth's crust of about 0.1%, generally occuring as phosphate in ...
Example of phosphorescence Monochrome monitor Aperture grille CRT phosphors. A phosphor is a substance that exhibits the phenomenon of luminescence; it emits light when exposed to some type of radiant energy.
Phosphates are the naturally occurring form of the element phosphorus, found in many phosphate minerals. In mineralogy and geology, phosphate refers to a rock or ore containing phosphate ions. Inorganic phosphates are mined to obtain phosphorus for use in agriculture and industry. [2] The largest global producer and exporter of phosphates is ...
White phosphorus munitions are weapons that use one of the common allotropes of the chemical element phosphorus. White phosphorus is used in smoke , illumination , and incendiary munitions, and is commonly the burning element of tracer ammunition . [ 1 ]
White phosphorus, yellow phosphorus, or simply tetraphosphorus (P 4) is an allotrope of phosphorus. It is a translucent waxy solid that quickly yellows in light (due to its photochemical conversion into red phosphorus ), [ 2 ] and impure white phosphorus is for this reason called yellow phosphorus.
The Israeli military deployed white phosphorus, a controversial and lethal chemical substance, in its war against Hamas, putting civilians at risk of life-threatening burns, according to the Human ...
White phosphorus munitions are not illegal and white phosphorus is not classified as a chemical weapon under the Chemical Weapons Convention. But international law requires militaries who use it ...
White phosphorus, yellow phosphorus or simply tetraphosphorus (P 4) exists as molecules of four phosphorus atoms in a tetrahedral structure, joined by six phosphorus—phosphorus single bonds. [1] The free P 4 molecule in the gas phase has a P-P bond length of r g = 2.1994(3) Å as was determined by gas electron diffraction . [ 2 ]
