information on phosphorous The first form of elemental phosphorus to be produced (white

phosphorus, in 1669) emits a faint glow upon exposure to oxygen – hence its name given from Greek mythology, Φωσφόρος meaning "light-bearer" (Latin Lucifer), referring to the "Morning Star", the planet Venus. The term "phosphorescence", meaning glow after illumination, originally derives from this property of phosphorus, although this word has since been used for a different physical process that produces a glow. The glow of phosphorus itself originates from oxidation of the white (but not red) phosphorus— a process now termed chemiluminescence.

Phosphorus is essential for life. As phosphate, it is a component of DNA, RNA, ATP, and also the phospholipids that form all cell membranes. Demonstrating the link between phosphorus and life, elemental phosphorus was historically first isolated from human urine, and bone ash was an important early phosphate source. Phosphate minerals are fossils. Low phosphate levels are an important limit to growth in some aquatic systems. The chief commercial use of phosphorus compounds for production of fertilizers is due to the need to replace the phosphorus that plants remove from the soil.

What is phosphorous ? Phosphorus is a chemical element with

symbol P and atomic number 15. A multivalent nonmetal of the nitrogen group, phosphorus as a mineral is almost always present in its maximally oxidized state, as inorganic phosphate rocks. Elemental phosphorus exists in two major forms—white phosphorus and red phosphorus—but due to its high reactivity, phosphorus is never found as a free element on Earth.

Date discovered and discovered by ?

Hennig Brand in 1669.

Uses of this element The chemical element phosphorus has many

uses and applications in everyday life. According to Nautilus, these applications include fireworks, luminous projectiles and matches. Phosphorus is also extensively used in industry for the production of metal alloys and as an additive to industrial oils. Its most popular application is in the fertilizer industry, which absorbs almost all extracted phosphates found in rocks.

Scientific events that happened in 1669

Astronomy and space exploration Biology:Marcello Malpighi publishes Dissertatio Epistolica

de Bombyce in London, a study of Bombyx mori which is the first published monograph on an invertebrate

Chemistry: Medicine : Meteorology and much more ! (example) Herbert Saffir and Bob Simpson develop the Saffir-

Simpson Hurricane Scale. Eugene Oregon had an record snowfall of 3 feet in 3 days

during late January. A pineapple express moved into the region with a shot of cold air, then there was some snow showers after that.

More Facts about phosphorous Phosphorus is classified as an element in

the 'Non-metals' section which can be located in groups 14,15 and 16 of the Periodic Table. Non-metals are not easily able to conduct electricity or heat and do not reflect light . Non-metallic elements are very brittle, and cannot be rolled into wires or pounded into sheets. Non-metallic elements exist, at room temperature, in two of the three states of matter : gases (such as oxygen) and solids (such as carbon).
