PhosphorusPhosphorus is an element discovered by Hennig Brand and Antoine Lavoisier in 1969. Phosphorus owes its name to the Greek word phosphorus also meaning "bearer of light", a saying from the ancient name of the planet Venus. the element was prepared through experiments with urine and bone ashes, the two experiments were carried out separately with different scientists. urine was tested by Mark and bone ash was tested by Lavoisier. The urine experiment lasted 2 weeks per lane using 50-60 buckets of urine for each experiment. Atoms and ions: Phosphorus has a central phosphorus atom and 4 oxygen atoms in tetrahedral arrangements. the phosphate ion carries a negative formal charge 3 and is the conjugate base of the hydrogen phosphate ion (HPo24) also base of (h2po42) the dihydrogen phosphate ion. Phosphorus has many physical properties, including - it is a solid - it has a density of ...phosphorus is a multivalent non-metal of the nitrogen group. It is found in several natural allotropic forms. These are the main forms. White phosphorus: white phosphorus is molecules made up of four atoms in a tetrahedral structure. a waxy solid known as tetraphosphorus that quickly turns yellow when exposed to light or takes on a greenish color when placed in dark areas or exposed to oxygen. White phosphorus is toxic and causes serious liver damage if inhaled or consumed. White phosphorus also smells like garlic. Red phosphorus: Red phosphorus is formed by heating white phosphorus to 250°C or by exposing white phosphorus to sunlight. it does not ignite at a temperature below 240°C. this is also what you find on matches.hittorf violet phosphorus: hittorf was a scientist who heated...... middle of paper ......the sphorus can cause symptoms such as loss of appetite, anxiety, bone pain, brittle bones, joint stiffness, fatigue, irregular breathing, irritability, numbness, weakness, poor growth of bones and teeth, and weight change. having too much phosphorus is more common and more dangerous than having less in our body, having too much phosphorus and less calcium can damage bones and cells. To stop osteoporosis, phosphorus and calcium levels must be close enough or completely equal. Elemental phosphorus is very toxic and used only for homeopathic treatment. The only non-toxic phosphates are natural, named above, phosphates found in foods, and dibasic potassium next. phosphatemono basic potassium phosphatesodium tribasic phosphatesodium dibasic phosphatesodium mono basic phosphatephosphatidl chlorinephosphatidl serine
