In the periodic table of elements Phosphorus has atomic number 15 and symbol P. It is a non-metal of the nitrogen group. At room temperature it is solid, but above 44.15 ° C it immediately becomes liquid.
Phosphorus is not found in nature in the elementary state, but in the form of phosphate (salt of phosphoric acid), it is abundant in some rocks and in the cells of living beings, of which it is an essential component of the metabolism.
The first matches were made with white phosphorus, but it was dangerous and toxic to handle. Exposure to the vapors caused the workers to necrosis of the jaw bones. With the adoption of the less volatile and more stable red phosphorus, the risks were reduced. White phosphorus was used in several wars as an incendiary weapon.
The Phosphorus is used:
- in the production of fertilizers
- phosphates are used in special glasses for sodium lamps;
- calcium phosphate is used for the production of porcelain and for the production of calcium mono-phosphate, used as a leavening agent;
- it is used in the production of special steels and bronzes;
- trisodium phosphate is used to soften the water and prevent blockages from limescale;
- white phosphorus is used in the war industry for the production of incendiary devices, smoke bombs and tracer projectiles.
- several phosphorus compounds are used in the manufacture of matches.
- phosphorus is used in the doping of semiconductors to increase their conductivity.
The giveaway
We are at the beginning of a new weekend (less time zone, more time zone), so you need something easy to be able to insert the phosphorus in your wallet.
I would have liked to see a picture of all of you blowing out a phosphorus match, but I'm good and I'm happy with a comment with your wax address.
Prize for the first 50 who will comment on the article with their wax address.
The previous giveaway sold out in less than 3 hours. I'm sorry for all those who remain excluded, but we are thinking of something interesting for aficionados.
The Periodic Table NFT project
The Periodic Table NFT project aims to raise awareness of chemical elements in a modern key, basing the approach on blockchain and Non Fungible Token.
Day after day it will be possible to know the single elements that make up the table, to collect curiosities about each of them and about the table in general.
We are working to be able to learn, in a playful way, also what happens by combining the various elements.
The whole project is based on the collection of NFTs that can be bought on the site https://wax.atomichub.io/market?collection_name=periodicelem&order=desc&sort=created&symbol=WAX or by participating in simple giveaways published on publish0x.
