Nickel – An Essential Element for Modern Applications

Introduction to Nickel:

Nickel is a chemical element that belongs to the transition metals group on the periodic table. It is denoted by the symbol “Ni” and has an atomic number of 28. With an atomic weight of approximately 58.69 atomic mass units, nickel is a relatively dense and lustrous metal. Its name is derived from the German word “kupfernickel,” which means “devil’s copper” due to its unusual ore that resembled copper but yielded no copper metal.

Nickel is commonly found in the Earth’s crust and is extracted from various mineral ores, such as pentlandite and pyrrhotite. It is widely used in numerous industries, including manufacturing, construction, and electronics. The outstanding properties of nickel, such as corrosion resistance, high melting point, and magnetic properties, make it a valuable material for various applications.
