Sodium has atomic number 11 and symbol Na, deriving from the Latin name Natrium. It is a soft, waxy, silvery, reactive metal. It belongs to the category of alkali metals which is abundant in natural compounds. It is highly reactive, burns with a yellow flame, oxidizes on contact with air and reacts violently with water. When chopped into a fine enough powder, sodium ignites spontaneously in the water. However, this metal does not ignite in air below 388 K (115 ° C).
Although metallic sodium has some important applications, the main uses of this element lie mostly in the compounds it forms. In fact, millions of tons of chloride, hydroxide, sodium carbonate are produced every year.
It is used for:
- Medical use
- In certain alloys to improve their structure,
- In soap (in combination with fatty acids),
- As a cooling fluid and heat transport in fast nuclear reactors and in the valves of some endothermic engines.
CAUTION: Sodium powder is flammable in air and explosive in water. It is also corrosive when in contact with the skin. This metal must always be handled with care. Sodium must be stored immersed in liquid hydrocarbons or kept in an inert atmosphere. Contact with water and other substances that react with sodium should be avoided.
Sodium is relatively abundant in stars and the spectral line of this element is among the main ones in starlight. Sodium makes up about 2.6% of the earth's crust making it the fourth most abundant element and the first among the alkali metals.
For sodium NFT it was decided to produce a maximum supply of 299 items and dedicate 50 to this giveaway. The previous giveaways were sold out in a few hours and therefore the first 50 users who comment on this article with their wax address will receive a NFT for free.
A little reminder that the laboratory is working to form the first NFT molecule. More information in this article.
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.
