a chemical element (symbol P) with an atomic number of 15, that exists in several allotropic forms
It is used in the composition on the tips of friction matches, and for many other purposes
A chemical constituent (nutrient) essential for life Phosphorus is a primary nutrient necessary for plant growth
Phosphorus is a poisonous yellowish-white chemical element. It glows slightly, and burns when air touches it. a poisonous yellowish chemical substance that starts to burn when it is in the air, and shines in the dark. It is a chemical element : symbol P (phosphoros ). Nonmetallic chemical element, chemical symbol P, atomic number
occurs naturally in rock formations in the earth's crust, usually as phosphate Of high nutritive value to plants and animals, phosphates are used in fertilizers and as animal feed supplements They are also used in the manufacture of industrial chemicals and pharmaceuticals and as detergent builders High phosphate concentrations in surface waters may indicate fertilizer runoff, domestic waste discharge, or the presence of industrial effluents or detergents Although phosphates from these sources are usually poly-phosphates or organically bound, all will degrade to "ortho" or reactive phosphates with time If high phosphate concentrations persist, algae and other aquatic plant life will flourish eventually causing decreased dissolved oxygen levels in the water due to the accelerated decay of organic matter Phosphate measurement is used to control scale and corrosion inhibitor levels in boilers and cooling towers (http: //www chemetrics com/)
An element that forms 0 12% of the earth's crust, chiefly in the form of phosphates Its presence in steel is usually regarded as an undesirable impurity due to its embrittling effect, for this reason its content in most steels is limited to a maximum of 0 050%
a nonmetallic element of the nitrogen family that occurs widely, especially as phosphates 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
An element required for bone growth and metabolic energy Stored in teeth and bones, mainly in combination with calcium, phosphorus blood levels are affected by parathyroid, blood, and bone diseases
Phosphorus is a nonmetallic element Phosphorus compounds are major constituents in the tissues of both plants and animals In man, phosphorus is mostly concentrated in bone Some phosphorus-concentrated compounds play an important part in energy conversions and storage in the body In a pure state, phosphorus is toxic
A primary plant macronutrient, usually found in slow-leaching soil forms, that is a main component of nucleic acids, including energy-transmitting ATP, as well as phosphoproteins and phospholipids
A nutrient essential for growth that can play a key role in stimulating aquatic growth in lakes and streams
One of the primary nutrients required for the growth of aquatic plants and algae Phosphorus is often the limiting nutrient for the growth of these plants (See nitrogen )
An essential nutrient for plants and animals that is commonly applied to crops as a phosphate fertilizer Phosphorus can contribute to the eutrophication of lakes and other water bodies Sources of excess phosphorus include sewage and agricultural runoff
One of the elements essential for the growth of organisms Phosphorus is also commonly the limiting or least available nutrient for plant growth in freshwater ecosystems The primary source of phosphorus is from the earth in the form of phosphate rock
A poisonous nonmetallic element of the nitrogen group, obtained as a white, or yellowish, translucent waxy substance, having a characteristic disagreeable smell
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
(Kimya) White phosphorus (WP): the ordinary allotrope of phosphorus, a translucent waxy whitish or yellowish solid which is poisonous and very reactive; also called yellow phosphorus
(Kimya) Beyaz fosfor, fosfor elementinin bir alotropudur. Duman kamuflajı ve hedef tayininde ve aynı zamanda da bir yangın silahı olarak askeri alanda yaygın kullanım tarzları bulmuştur. Kısaca WP, veya white phos, veya tanımının başharflerinden yola çıkarak, Willie Pete olarak adlandırıldığı olmaktadır
