    The names of both elements have their origins in the frustrations of miners caused by metal-arsenic ores: nickel arsenide and cobalt arsenide. Cobalt's name is derived from the German 'kobold' meaning 'goblin' – a close relative of the creature from which nickel's name was derived. In cobalt's case, miners mistakenly thought the ore contained silver, and called the ore .
