As one of the world’s essential metals, Nickel has been used for thousands of years, and its use continues to grow. This article will provide you with a comprehensive guide on Nickel, its properties, where it is found, and how it is extracted.

Definition and Chemical Symbol/Formula of Nickel

Nickel is a chemical element that belongs to the transition metal group, with the symbol Ni and the atomic number 28. It is a hard, silvery-white lustrous metal with a density of 8.91 grams per cubic centimeter.

Nickel has an atomic mass of 58.69u and a melting point of 1453C and boiling point of 2732C. Nickel is magnetic at room temperature and has excellent corrosion resistance.

Properties and Characteristics of Nickel

Nickel is a ductile, malleable, and highly lustrous metal with high electrical conductivity. It can absorb up to 200 times its own volume of hydrogen gas, making it a significant component of catalysts that produce hydrogen gas.

Nickel is a good conductor of heat and electricity, as well as being highly resistant to corrosion. Nickel alloys are used in many industrial and engineering applications due to their excellent strength, durability, and resistance to corrosion.

Where Nickel is Found

Natural Occurrence of Nickel

Nickel is a widespread metal found in the Earth’s crust and the fifth most common element, making up around 0.008% of the Earth’s crust. It is obtained from two main types of deposits: Magmatic sulfide deposits and laterite deposits.

Sulfide deposits are found in igneous rocks, while laterite deposits are typically found in tropical regions that experience high rainfall.

Extraction of Nickel from its Ores

The process of extracting nickel from its ores is an intricate process that involves multiple steps. The two primary methods used to extract nickel from its ores are hydrometallurgy and pyrometallurgy.

Hydrometallurgy is the most common method used to extract nickel, where the ore is roasted to remove moisture and then leached with sulfuric acid to dissolve the nickel, which is then extracted from the solution using solvents. Pyrometallurgy is the process of extracting nickel using high temperatures, typically using carbon to reduce the nickel oxide to pure metal.

This process is highly energy-intensive and produces significant amounts of greenhouse gas emissions. Nickel is an essential component of many everyday items and has an array of industrial and medical uses.

This article has offered a comprehensive guide on nickel, highlighting its specification, properties, extraction, and uses.

The History of Nickel

Nickel is a metal that has been used by humans for more than 2500 years. The word “nickel” comes from the German word “kupfernickel,” meaning devil’s copper or false copper.

It was named this way because miners mistook nickel ore for copper and believed that it was evil because it did not yield any copper.

Origin of the Name Nickel

The history of the name “nickel” dates back to the 16th century when German miners discovered a red-colored ore that looked like copper but did not yield any copper. They believed that it was the work of the devil, and so they named it “kupfernickel” or “devil’s copper.” The name stuck, and eventually, it was shortened to simply “nickel.”

Discovery of Nickel

Axel Fredrik Cronstedt, a Swedish chemist and mineralogist, is credited with the discovery of nickel. In 1751, Cronstedt was experimenting with a new mineral he had found in the Swedish province of Uppland.

After analyzing it, he realized that it was a new element, which he named nickel. Cronstedt found that nickel was alloyed with arsenic, cobalt, and iron in the mineral, which he named “Nickeline.”

Nickel Identification

Atomic and CAS Numbers of Nickel

Nickel has an atomic number of 28 and a Chemical Abstracts Service (CAS) number of 7440-02-0. The atomic number represents the number of protons in the nucleus of a nickel atom, while the CAS number is used to identify specific chemical substances.
