Where and When?

Nickel was discovered by Baron Axel Frederik Cronstedt in 1751. Apparently, he had expected to extract copper from a mineral, instead obtaining instead a white metal that he called nickel after the mineral from which it was extracted.

Nickel is a natural element of the earth's crust: therefore, small amounts are found in food, water, soil and air.

Uses and Characteristics

Nickel is used in nickel alloys, electroplating, batteries, coins, industrial plumbing, spark plugs, machinery parts, stainless-steel, nickel-chrome resistance wires, and catalysts.

Characteristics: High melting point, 1453 ºC, resists corrosion and oxidation, very ductile, alloys readily, magnetic at room temperature, can be deposited by electroplating, and has catalytic properties.


Physical properties: Each can show their own physical properties, but examples are silvery-white metal, primarily combined with oxygen or sulfur as oxides,

Chemical properties: Nickel is not very reactive. It reacts very slowly with oxygen in the air.
