History

History
The element Tantalum was discovered by Anders Gustaf Ekeberg in year 1802 in Sweden. Tantalum derived its name from from King Tantalus, father of Niobe from Greek mythology
The element Gold was discovered by Middle East in year 2500 BC in unknown place. Gold derived its name derived its name from from English word (aurum in Latin)
