History

History
The element Antimony was discovered by unknown in year 3000 BC in unknown place. Antimony derived its name from from the Greek anti, 'against', and monos, 'alone' (stibium in Latin)
The element Tantalum was discovered by Anders Gustaf Ekeberg in year 1802 in Sweden. Tantalum derived its name derived its name from from King Tantalus, father of Niobe from Greek mythology
