Facts about phosphorus
Here are a few interesting facts about phosphorus element.
- It is believed that the phosphorus is present on the earth because of meteorites.
- Phosphorus element is the 11th most abundant element present in the earth’s crust.
- The amount of white phosphorus present in the earth’s crust is approximately 1050 ppm by weight.
- The phosphorus element is also found in the human body and it is approximately 750 grams. The bones as well as DNA and RNA contain phosphorus.
- The pure phosphorus can harm the human body.
- White phosphorus causes chemical burns, when it comes in contact with the human body.
Properties of phosphorus
Here is a list of some physical properties and chemical properties of phosphorus.
Physical properties of phosphorus
- Phosphorus has a waxy white appearance, but it is also found in other colors like red, yellow, and metallic color.
- As phosphorus is a nonmetal, it is a bad conductor of heat and electricity. But the phosphorus that is having a metallic color can conduct electricity.
- The melting point and boiling point of white phosphorus are 44.15 °C and 280.5 °C respectively.
- The white phosphorus glows in the air.
Chemical properties of phosphorus
- Phosphorus is always found with other elements in the earth’s crust because it is a chemically reactive element.
- White phosphorus is very reactive and because of this reason, it is kept in water.
- Phosphorus forms phosphides when it is heated with metals.
- Phosphorus also reacts with halogens.
- Phosphorus has many isotopes, but the only stable isotope is 31P.
Uses of phosphorus
Here are some uses of the phosphorus element.
- The main use of phosphorus is in making fertilizers.
- Sodium triphosphate is a compound of phosphorus that is used in making detergents.
- The red phosphorus is used on the matchbox for igniting the matchsticks.
- Dicalcium phosphate is a compound of phosphorus that is used in toothpaste which acts as a polishing agent.
- Flares, LEDs as well as matchsticks also use phosphorus.
