Nickel: meaning, definitions and examples

The term 'nickel' derives from the German word 'Kupfernickel', meaning 'false copper'. This name was given to a nickel ore in the 18th century that resembled copper ores but was not beneficial for extracting copper. The confusion led early miners to feel tricked, hence the use of 'nickel' as a reference to something misleading or worthless. The element itself was first isolated by Swedish chemist Axel Fredrik Cronstedt in 1751. The use of nickel in coinage began in the 19th century, particularly in the United States, where the five-cent piece became known as a 'nickel'. Today, nickel is essential in various industries, including electronics and electroplating, due to its unique properties.
