All About Nickel: History, Invention, Few Critical Applications, Properties And Significance
For many thousands of years, men have used nickel in a lot of their needs. Back then, they weren't aware of the chemical characteristics of the element and that they could use nickel alloys in many purposes as well.
What is nickel?
Nickel is a versatile metal, a chemical element, with an atomic number of 28 and chemical symbol Ni. It's shiny and often silvery-white in look. It is a ferromagnetic component that can exist in normal temperature. There're only three other elements which possess the same characteristic: gadolinium, iron and cobalt.
How was nickel discovered?
It is believed that man has used nickel as early as 3500 BC. However, it was only in 1751 that it was classified and recognized as a chemical component by Swedish chemist & mineralogist Axel Fredrik Cronstedt who, for the first time, thought it was a copper mineral. Since then, essential nickel ore minerals are discovered, such as limonite, pentlandite and garnierite.
What are the properties of nickel?
The characteristics of nickel are divided into atomic, physical, isotopes, and chemical. Its atomic characteristics include its electronic configuration, electron structure, and any other electron-related stuff.
Its physical properties include its color (that's silvery-white), magnetic abilities (like what was mentioned earlier, it is among the 4 elements that have magnetic abilities at room temperature, but is non-magnetic when exposed to temperature greater than that), & unit cell structure (nickel has a face centered cubic unit cell). It is also ductile and hard.
Nickel has five stable isotopes, each of which has an unique listing of properties and characteristics. And when we speak of nickel's chemical properties, it takes place in many oxidation states. The most typical among them all is +2.
Where is nickel used?
Many industries today make use of nickel in their operations. Many of the products which use nickel are rechargeable batteries, stainless steel, coinage, electrical guitar strings, magnets, nickel alloys and any other sorts of alloys, together with bronze, copper, lead, silver, gold, cobalt, aluminum & chromium. It is also used to make nickel cast irons and nickel steels.
Nickel alloys are usually used in power plants, gas and oil plants, and any other processing factories. They are excellent at corrosion resistance and heat regulation. They're also utilized in nuclear reactors and solar engineering. In our home, nickel alloys are found in our electrical heaters, cookers and any other appliance.
