Everything About Nickel: History, Invention, A Few Critical Applications, Characteristics & Signific

For many thousands of years, men have used nickel in a lot of their needs

. Previously, they were not conscious of the chemical characteristics of the component and which they could use nickel alloys in many different purposes also.

What is nickel?

Nickel is a versatile metal, a chemical component, with an atomic number of 28 and chemical symbol Ni. It's glossy and often silvery-white in look. It's a ferromagnetic element which can exist in room temperature. There are only 3 other components that have the same characteristic: gadolinium, iron and cobalt.

How was nickel discovered?

It is believed that man has used nickel as early as 3500 BC. But, it was only in 1751 that it was classified and recognized as a chemical element by Swedish chemist & mineralogist Axel Fredrik Cronstedt who, at first, thought it was a copper mineral. Since then, essential nickel ore minerals are discovered, like limonite, pentlandite and garnierite.

What are the properties of nickel?

The properties of nickel are divided into atomic, physical, isotopes, and chemical. Its atomic properties include its electronic configuration, electron structure, and any other electron-related stuff.

Its physical characteristics include its color (which is silvery-white), magnetic abilities (like what was stated earlier, it is among the 4 elements which have magnetic abilities at room temperature, but is non-magnetic when exposed to temperature more than that), and unit cell structure (nickel has a face centered cubic unit cell). It is also ductile and hard.

Nickel has 5 stable isotopes, each of them 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 commonest among them all is +2.

Where is nickel used?

Plenty of industries nowadays use nickel in their operations. Many of the products that use nickel are rechargeable batteries, stainless steel, coinage, electric guitar strings, magnets, nickel alloys and other types of alloys, including bronze, copper, lead, silver, gold, cobalt, aluminum & chromium. It is also used to make nickel cast irons and nickel steels.

Nickel alloys are commonly used in power plants, gas and oil plants, and other processing factories. They're good 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 electric heaters, cookers and other appliance.
