Technetium is the chemical element with atomic number 43 and its symbol is Tc.
It is a silvery gray element, radioactive, transition metal of the fifth period, crystalline very rare in nature; technetium is one of the natural and artificial nuclear fission products of uranium and is used in nuclear medicine to obtain scintigraphic and tomographic images of numerous body compartments
The word technetium derives from the Greek τεχνητός (technetos), "artificial". It owes its name to the fact that it was artificially produced in nuclear reactors, since it is not present on Earth. It was the first element to be artificially produced.
Technetium is an excellent corrosion inhibitor for steels and is an excellent superconductor at temperatures below 11 K. It is a radioactive β emitter element that is obtained from the uranium fission products of nuclear reactors where it constitutes 6% of the total.
Given its rarity and radioactivity it has practically no use as a metal.
Technetium is one of the most effective rust protectors and is also a valuable source of beta rays.
For many years there was a gap in the periodic table in place of element number 43. Dmitry Mendeleev predicted that the missing element should be chemically similar to manganese and therefore named it ekamanganese. In 1925 Walter Noddack and Ida Tacke, the discoverers of rhenium, announced the discovery of element 43 calling it masurium (from Masuria, a region of East Prussia, now Polish), but their announcement was never confirmed and today it is commonly considered erroneous. Although some researchers have disputed this conclusion. Technetium (from the Greek technetos, artificial) was discovered in the laboratories of the Physics Institute of the University of Palermo in 1937 by Carlo Perrier and Emilio Segrè in Sicily.
The giveaway
The first artificially created element of the periodic table needs some innovation in the giveaway organization.
So far all previous giveaways have moved on an assignment that is among the fastest to comment and draws. We have organized them in various ways and proportions.
For this giveaway we will insert a new assignment group based on your willingness to share the project with your social channels.
This item has a max supply of 200 and 130 pieces are dedicated to the giveaway.
To participate, simply comment this article with your WAX address by April 8 at 16:00 CEST. Optionally you can add the link of your tweet, your facebook post, your story on instagram or any other social initiative in which you present to your friends why you are participating in this giveaway. The social message must be after the publication of the article and written before the deadline.
As a first assignment, among all those who have inserted the link to their social sharing in the comment of the article, 30 NFTs will be extracted (social group).
Subsequently, the 30 fastest comments will be awarded (which have not already been awarded in the social group).
Finally, among all the others, a second draw will be made to assign the remaining 70 NFTs.
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.
