Term Symbol 3F 4
Discovery It was discovered by the Swedish metallurgist Axel-Frederik Cronstedt (Stockholm, Sweden) in 1751.
Name Derived From

The name derives from the German nickel for "deceptive little spirit" because miners called mineral niccolite (NiAs) by the name Kupfernickel (false copper, Devil's copper or St. Nicholas copper') because it resembled copper ores in appearance, but no copper was found in the ore.
