Name Origin Greek: phos (light) and phoros (bearer). "Phosphorus" in different languages. Sources Due to its high reactivity, it is never found as a free element in nature. Found most often in phosphate rock, which is partly made of apatite (Ca5(PO4)3(OH, F, Cl)).Abundance Universe: 7 ppm (by weight) Sun: 7 ppm (by weight) Carbonaceous meteorite: 1100 ppm Earth's Crust: 1000 ppm Seawater: Atlantic surface: 1.5 x 10-3 ppm Atlantic deep: 4.2 x 10-2 ppm Pacific surface: 1.5 x 10-3 ppm Pacific deep: 8.4 x 10-2 ppm Human: 1.1 x 107 ppb by weight 2.2 x 106 ppb by atoms Uses Used in the production of fertilizers, fireworks, matches, pesticides, toothpaste and detergents. White phosphrous is used in military applications as incendiary bombs and for smoke screens. Calcium phosphate is used in the production of fine China. It an important component in steel production, in the making of phosphor bronze, and in many other related products. Red phosphorus is essential for manufacturing matchbook strikers, flares, and, most notoriously, methamphetamine. History Phosphorus (Greek phosphoros was the ancient name for the planet Venus, but in Greek mythology, Hesperus and Eosphorus could be confused with Phosphorus) was discovered by German alchemist Hennig Brand in 1669 through a preparation from urine, which naturally contains considerable quantities of dissolved phosphates from normal metabolism. Working in Hamburg, Brand attempted to distill some salts by evaporating urine, and in the <b>...</b>
