Phosphorus is a member of the pnictogens, together with nitrogen, arsenic, antimony, bismuth, and moscovium, and consequently shares properties with them. Phosphorus is an element essential to sustaining life largely through phosphates, compounds containing the phosphate ion, PO 3− 4.
The developing sciences of chemistry and Paleontology, combined with the discovery of coprolites in commercial quantities in East Anglia, led Fisons and Packard to develop sulfuric acid and fertilizer plants at Bramford, and Snape, Suffolk in the 1850s to create superphosphates, which were shipped around the world from the port at Ipswich. By ...
The phosphorus cycle is the biogeochemical cycle that involves the movement of phosphorus through the lithosphere, hydrosphere, and biosphere.Unlike many other biogeochemical cycles, the atmosphere does not play a significant role in the movement of phosphorus, because phosphorus and phosphorus-based materials do not enter the gaseous phase readily, [1] as the main source of gaseous phosphorus ...
The largest colony of bats in the world at Bracken Cave (about 20 million individuals) deposit 50,000 kg (110,000 lb) of guano into the cave every year. Even smaller colonies have relatively large impacts, with one colony of 3,000 gray bats annually depositing 9 kg (20 lb) of guano into their cave.
The Phosphoria includes phosphorite beds that are an important source of phosphorus. [5] Many of its shales are rich in organic matter and are petroleum source rocks, [6] and some of its dolomites include petroleum reservoirs. [7]
People exposed to white phosphorus can suffer severe and sometimes deadly bone-deep burns. It can cause organs to shut down, and burns on just 10% of the body can be fatal, HRW said.
Phosphorus (P) 15 φῶς + φόρος (phos + phoros) Greek via Latin [14] "light-bearer" descriptive From Greek φῶς + φόρος (phos + phoros), which means "light bearer", because white phosphorus emits a faint glow upon exposure to oxygen. Phosphorus was the ancient name for Venus, or Hesperus, the Morning Star. [3] Sulfur (S) 16 Old ...
CRT phosphors were standardized beginning around World War II and designated by the letter "P" followed by a number. Phosphorus , the light-emitting chemical element for which phosphors are named, emits light due to chemiluminescence , not phosphorescence.
