PRODUCT DETAILSAllotropes and compounds of phosphorus have many important uses, most elemental phosphorus is used in the production of pho*sphoric acid, which is a solid used in the production of triphosphate fertilizers, and some soils require large amounts of phosphorus in order to grow crops. Red phosphor can be formed by heating white phosp*horus or exposing it to sunlight. It is very different from explosive white phosp*horus. For example, when scratched on a surface, a safety match head made of red phosphorus will change back to white pho*sphorus and ign*ite due to the slight friction of the match on a rough surface. Red phosphorus is also used in fireworks, bombs, and pesticides, and in the manufacture of phos*phoric acid, electroluminescent paints, and fertilizers. Phosphorus is an essential element for living things. It is an essential component of tissues (especially bones and teeth) and cells, is a Chemicalbook necessary for the formation of nucleic acids and energy-carrying molecules such as ATP, and is also involved in various metabolic reactions. Phosphorus (P) is an important nutrient for plants. It is a non-metallic element with atomic number 15. It belongs to Group 15 of the periodic table. Phosphorus is used up to one-tenth of nitrogen. The amount of phosphorus in most plants is between 0.1% and 0.4%, which is significantly lower than the amount of potassium and nitrogen in plants. Phosphorus is an important component of the nucleoproteins in the nucleus that control cell division and the DNA molecules that pass on inherited genes to living organisms. Phosphorus also plays an important role in (a) stimulating early root growth, (b) promoting plant maturation, (c) converting intracellular energy, and (d) enabling fruit and seed development and ripening. Phosphorus is rightly called the key to life because it is directly involved in most life processes.
