Iodine is the chemical element with atomic number 53 and its symbol is I.
It belongs to the group of halogens. Iodine is found in many oxidation states, including iodide, iodate and various periodate anions.
It is an element that, in trace amounts, is involved in the metabolism of many living beings, including humans. Iodine is found in thyroid hormones. Iodine deficiency affects approximately two billion people and is the leading preventable cause of intellectual disability.
The largest producers of iodine today are Chile and Japan. Iodine and its compounds are mainly used in nutrition. Thanks to its high atomic number and ease of attachment to organic compounds, it is widely used in radiology as a non-toxic contrast medium. Given the specificity of its absorption by the human body, radioactive isotopes of iodine can also be used to treat thyroid cancer. Iodine is also used as a catalyst in the industrial production of acetic acid and some polymers.
Iodine is a dark, bluish-violet solid with an almost metallic sheen that even at room temperature sublimates into a violet vapor with an irritating smell.
Among other uses:
- Iodine tincture is a 3% hydroalcoholic solution of triiodide used as a disinfectant for external use and for the disinfection of surface water (3 drops per liter, leaving it to act for 30 minutes);
- Povidone iodine is an iodine compound, one of the best disinfectants available today. There are commercially available iodine-based compounds to disinfect water, although it has some contraindications. A povidone-based preparation is required by law in the first aid kit in companies and in the workplace.
- Iodine compounds are very useful in the synthesis of organic compounds;
- Potassium iodide is used in photography
- Potassium iodide is also used as a preventative prophylaxis for people exposed to the consequences of nuclear disasters: taking potassium iodide decreases the likelihood that the human body will absorb the radioactive iodine produced by the disaster; during 1986 the USSR, following the Chernobyl Disaster, was distributed to the population in the form of tablets, in order to avoid the absorption of radioactive iodine by the thyroid, which could lead to the formation of tumors;
- Tungsten iodide is used to stabilize the filaments of light bulbs;
- Iodine-123 and iodine-125, gamma-emitting radioactives, are used as tracers in medicine.
- Iodine plays a fundamental role in determining the amount of dissolved oxygen in water (Winkler's method).
The giveaway
With this element we play with the most classic formula used in giveaways: speed and luck.
The max supply of the item is 200 pieces and 50% is for the giveaway. The split between speed and luck is also set to 50%. This means that they will be rewarded:
- the first 50 users who will comment on the article with their WAX wallet
- among all the others who will leave the comment by 10 September at 16:00 CEST, 50 NFT winning wallets will be extracted
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.
