Krypton is a chemical element with the symbol Kr and atomic number 36. It is the last element of period 4 (row 4) of the periodic table. It belongs to the group of noble gases, is colorless and is present in traces in the atmosphere.
Krypton is one of the products obtained from the nuclear fission of uranium.
Krypton finds application in particular flash lamps for photography; it has also been used since the 2000s in the bulbs of some incandescent bulbs to extend the life of the filament.
In 1960 an international agreement defined the meter in terms of the wavelength of light emitted by a krypton isotope. This agreement replaced the standard meter kept in Paris, a metal bar made of platinum and iridium and was estimated to be the forty millionth part of the earth's meridian. In October 1983 the krypton standard was in turn replaced by the International Bureau of Weights and Measures: one meter is now defined as the distance that light travels in a vacuum in a time of 1/299 792 458 seconds.
Krypton is considered a non-toxic asphyxiant. It has a narcotic potential seven times higher than that of atmospheric air: if breathed in large quantities it can therefore induce narcosis, similar to the stress of diving to great depths.
How many of you think of Superman when it comes to Krypton? Krypton is a fictional planet, created in the Superman comics as the home planet of the superhero invented in 1938. When the planet Krypton exploded, its fragments, kryptonite, spread throughout space. Many of them also reached Earth, with a certain consistency over the years. For humans, kryptonite is apparently harmless, but due to its particular radiological conformation, it is capable of harming any Kryptonian.
But that's another story ....

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.
