Ekeberg discovered tantalum in 1802. It occurs principally in the mineral columbite-tantalite.
Tantalum has no known harmful effects on the human body, so it is used in manufacturing
surgical equipment. It is in manufacturing aircraft and missile parts. It is named after "Tantalus",
Greek mythological figure and father of Niobe.
