Strontium is the chemical element with atomic number 38 and whose symbol is Sr. It belongs to the group of alkaline-earth metals and appears as a soft, silvery, white or slightly yellow metal; when exposed to air it forms a dark oxide layer.
In nature it occurs mainly in celestite and stronzianite.
Both strontium and strontianite are named after Strontian, a village in Scotland near which the mineral was discovered in 1790.
In the 19th century, the most important application of strontium was the production of sugar from beets. During the peak production of cathode ray tubes, approximately 75% of the consumption of strontium in the United States was destined for the making of the front glass. With the introduction of other types of monitors, the consumption of strontium has dropped dramatically.
Other industrial and commercial uses include:
- production of ferrite magnets and zinc refining;
- optical applications of strontium titanate, due to its extremely high refractive index and its dispersing power higher than that of diamond; it is also used as a gem, although rarely because it is fragile and easily subject to abrasion;
- production of fireworks to which strontium salts give the red color;
- production of toothpastes for sensitive teeth, in the formula of which strontium chloride is sometimes present;
- production of thermoplastic materials such as plastoferrite.
- use in atomic interferometry experiments and use in atomic clocks.
With the previous element we had organized a maxi giveaway to celebrate the fifth period of the periodic table, giving away 90% of the entire supply: it was not sold out.
So we decided to repeat the experiment. Also this time 90% of the entire supply of this element will be at stake, with fewer days to participate. The reason we want to celebrate is the rise of WAX in recent days.
Strontium has a max supply of 200 NFTs and 90% of the entire supply is dedicated to this giveaway. This is 180 NFTs awarded with a draw from all those who comment on this article with their WAX address by March 11 at 16:00 CEST. If the comments were less than 180 it means that everyone will receive this NFT as a gift (a user-a wallet).
In the next few days, the NFTs of Rubidium and the two new molecules will be sent.
And also this time we are looking for a new experiment: publish the article in the evening (European) and give the news on our channels the following morning (there is no assignment for response speed).
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.
