How do we use phosphorus in everyday life?
Today most of our phosphorus comes from phosphate rock that is mined around the world, and then converted to phosphoric acid. Fifty million tonnes are made every year and it has multiple uses. It is used to make fertilisers, animal feeds, rust removers, corrosion preventers, and even dishwasher tablets.
What do we use phosphorus for?
Function. The main function of phosphorus is in the formation of bones and teeth. It plays an important role in how the body uses carbohydrates and fats. It is also needed for the body to make protein for the growth, maintenance, and repair of cells and tissues.
Is phosphorus a positive or negative ion?
The main known forms of the element are white, red, and black phosphorus. In addition, there are hundreds of compounds in which phosphorus is present as an anion, a negatively charged ion. Some of these compounds have very useful properties.
What are the properties and uses of phosphorus?
Phosphorus (P) is essential for all living organisms. Plants must have phosphorus for normal growth and maturity. Phosphorus plays a role in photosynthesis, respiration, energy storage and transfer, cell division, cell enlargement and several other processes in plants.
What are facts about phosphorus?
Phosphorus is an essential mineral primarily used for growth and repair of body cells and tissues. According to the University of Maryland Medical Center , all body cells contain phosphorus, with 85 percent found in bones and teeth. There, together with calcium, phosphorus provides structure and strength.
Which is the most reactive form of phosphorus?
White phosphorus is the least stable, the most reactive, the most volatile, the least dense, and the most toxic of the allotropes. It gradually changes to red phosphorus, a transformation accelerated by light and heat.
What element has atomic number 15?
Atomic Number 15 Element Facts. The green glow is emitted by phosphorus, atomic number 15, in the presence of oxygen, atomic number 8. Phosphorus is the element that is atomic number 15 on the periodic table.
