Key Notes On What Is Phosphorus

In 1669, in Hamburg, Hennig Brandt synthesised phosphorus for the first time when he evaporated urine and heated the residue until it was red hot, generating phosphorus vapour, which he recovered by condensing the residue in water. Because he believed he had discovered the Philosopher’s Stone, which could turn base metals into gold, Brandt kept his discovery a secret. When he ran out of money, he sold phosphorus to Daniel Kraft, who exhibited it all across Europe, including in London, where Robert Boyle was completely intrigued. He figured out how it was created and did a comprehensive investigation. Ambrose Godfrey, his helper, made a fortune by launching his own phosphorus manufacturing and distribution company.

It was a major changer when it was discovered that bone was made up of calcium phosphate and could be utilised to make phosphorus. There are two forms of phosphorus mainly which are white phosphorus and red phosphorus. White phosphorus is a dangerous waxy substance that, if it comes into contact with the skin, can inflict severe burns. When exposed to air, it glows in the dark and catches fire spontaneously. Amorphous red phosphorus is a non-toxic substance.

Properties Of Phosphorus 

• Phosphorus is considered as a  multivalent nitrogen-based nonmetal.
•  It can be found in nature in a variety of allotropic forms and is a vital component of organisms’ survival.
• White, red, and black phosphorus are three separate types of phosphorus, albeit their colours are more likely to differ somewhat. 
• The one used in industry is white phosphorus, which lights in the dark, is spontaneously combustible when exposed to air, and is a lethal toxin. 
• Red phosphorus ranges from orange to purple as the element has a tiny difference in its chemical structure.
• The third form, black phosphorus, is created under great pressure, resembles graphite, and can conduct electricity like graphite

Applications Of Phosphorus 

• Fertilisers with concentrated phosphoric acids are used in agriculture and farm productivity. 
• Phosphates are employed in pyrotechnics, pesticides, toothpaste, and detergents, as well as for special glassware, sodium lamps, steel production, military applications (incendiary bombs, smoke screens etc).
• The substance attached on the side of matchboxes, which is used to strike safety matches against to ignite them, contains red phosphorus.

Occurrences Of Phosphorus In The Environment

Phosphorus is never found in its pure form in nature, but only as phosphates, which are made up of a phosphorus atom coupled to four oxygen atoms. This can be found in rocks as the negatively charged phosphate ion (PO43-) or as organophosphates, which have organic molecules bonded to one, two, or three of the oxygen atoms. There are numerous different types of phosphate minerals, with apatite being the most common.  Russia, the United States, Morocco, Tunisia, Togo, and Nauru are the primary mining countries. The global production capacity is 153 million tonnes per year. Concerns have been raised and it is alarming as to how long these phosphorus deposits will last as phosphorus is such an important element in fertilisers, its depletion could pose a severe threat to global food production. Phosphate concentrations in the oceans are extremely low, especially near the surface. The reason for this is partly due to the insolubility of aluminium and calcium phosphates, but phosphate is quickly depleted in the oceans and settles to the bottom as organic waste. Phosphate levels in rivers and lakes may be higher, resulting in excessive algae development.

Effect Of Phosphorus On Human Health

• Phosphorus is most typically found in the environment as phosphates. Phosphates are significant molecules in the human body because they are a component of DNA and help to distribute energy. 
• By adding phosphate-rich manures to the soil and using phosphate-containing detergents, humans have drastically altered the natural phosphate supply. 
• Phosphates were also used in the manufacture of cheese, sausages, and hams. Too much phosphate in the body can lead to health issues like renal damage and osteoporosis. 
• Phosphate shortages are also a possibility as these are brought on by a heavy dose of drugs. Phosphate deficiency can lead to health issues.
• The majority of those who died from white phosphorus poisoning did so by inadvertently eating rat poison. People who have been exposed to white phosphorus frequently experience nausea, stomach cramps, and lethargy before dying.
• Skin burns can be caused by white phosphorus. When white phosphorus is burned, it can harm the liver, heart, and kidneys.

Conclusion

Phosphorus (P) is a chemical element with an atomic number of 15 belonging to the nitrogen family (Group 15 [Va] of the periodic table) that is a colourless, semitransparent, soft, waxy solid that glows in the dark at room temperature. The atomic structure includes 15 protons and 15 electrons.  It is a vital component of the human body that can be found in a wide range of products, including pesticides and detergents. Phosphorus is an element that one will under no circumstances  find freely in our environment. Preparation of fertilisers is by far the most common usage of phosphorus compounds. Phosphate ores are used to make ammonium phosphate. Before being turned into ammonium phosphate, the ores must first be transformed into phosphoric acids.
