Phosphorus was discovered in 1669, Germany. Henning Brand a German alchamnist discovered phosphorus by distilling urine. While Henning Brand was working in Hamburg, He attempted to distill salts by evaporating urine, and in the process that he had created Phosphorus.

Although it is thought that Arabian alchamists discovered Phosphorus in the 12th century, Henning brand is credited.

The word Phosphorus fits the element correctly because in Greek "phos" means light and "phorus" means bearer so all together it mean light bearer.

Phosphorus has many properties, both chemical and physical. It has many properties because of many forms of phosphorus.

The properties of white phosphorus are fire. It is highly reactive and explodes. It is waxy and found as a solid. The high reactivity of white phosphorus involved in the bonding of four phosphorus atoms in a tetrahedral configuration. This means that phosphorus will bond with atoms very quickly. Its melting point is 44 degrees Celsius and its boiling point is 280 degrees Celsius. White phosphorus also glows and turns yellow when exposed to the sun.

Red phosphorus may be formed by heating white phosphorus to 250°C. Red phosphorus does not catch fire in air at temperatures below 240°C, whereas white phosphorus ignites at about 30°C. Red phosphorus is also flammable.

Black phosphorus is the thermodynamically stable form of phosphorus at room temperature and pressure. It is created by heating white phosphorus under very high pressures (12,000 atmospheres) Black phosphorus is like graphite, being black and flaky. It is also a conductor of electricity.

Phosphorus is very important for the human body and for health. Phosphorus is found in bones, teeth, nucleic acids, in the energy carriers, lipids, proteins and enzymes. This shows the importance of phosphorus to the health of body in general and bones and teeth in particular. These are all parts of the body in which Phosphorus is found in which is cells and bones. Phosphorus also helps bone formation, digestion, excretion, protein formation, hormone balance, energy extraction, cell repair, chemical reactions, and nutrient utilization. The health benefits of phosphorous make it an important constituent of one’s diet.

So you see phosphorus is very important in our body, without things like this would happen: weak bones and discomfort in various body joints which would be a strange feeling. Also phosphorus shares a space with calcium in providing strength to bones, its deficiency may lead to weakness, tooth decay, rickets and other related bone problems. You may also experience loss of appetite and degraded body stamina. Along with all these, deficiency of phosphorus may also invite numbness, anxiety, tremors, loss of weight and restricted growth.

Phosphorus is used in many materials like matches. It used to be that white phosphorus was used to create fire but now red is because it is less reactive. The reason they switched it to red phosphorus because 0.1 grams of white phosphorus could kill you and was highly reactive.

Also phosphorus is used against fire ironically. The element it self is used for fire but the chemicals that are taken out of it which are chemical compounds are used in fir retardants.

Phosphorus is also used as a lubricant against high temperatures. Phosphorus is also used for treating metals or coating them. In metal uses it is used for protecting the metal or cleaning it.

Phosphorus is also used in fertilizers. Phosphorus is one of the most important elements for the plants. Phosphorus is important for plants because it help the plant cells. Also phosphorus is used in pesticides, which is meant for killing insects from eating plants.

Another important use for phosphorus is tooth paste. Phosphorus is used as a cavity protection. It also used in shampoo to clean your body.

Phosphorus is also used in bombs and chemical weapons. White phosphorus is the most reactive and is used in bombs or chemical weapons. It is meant to be shot up into the air and illuminate the ground showing all enemies but is also shot at enemies and buildings as an in cinerary weapon, which means to burn or vaporize.

Phosphorus exists in 10 allotropic forms. These forms occur within three major categories which are white or yellow phosphorus, red phosphorus, and violet or black phosphorus.

White phosphorus is the most dangerous because of how unstable it is. White phosphorus almost reacts to everything and explodes or sets a fire quickly. White phosphorus may be made by several methods. One of the methods is tri-calcium phosphate, the main ingredient of phosphate rocks. When the tri-calcium is taken out it is heated in the presence of carbon and silica in an electric furnace or fuel fired furnace.

Red phosphorus is harmless. It is used in matches and things like that. It is extracted from phosphate rocks.

Black and violet phosphorus is flaky like graphite and is made by subjecting white phosphorus to high pressures. It is chemically the least reactive form.

Phosphorus is found on earth in water, soil and sediments. Phosphorus is most commonly found in rock formations and ocean sediments as phosphate salts. Phosphate salts are released from rocks through weathering and usually dissolve in soil or water and will be absorbed by plants.

Phosphorus is found in plants, animal and humans. It is not used or taken out of plant or animals it is there to help the body develop and repair things.
