History

History
The element Arsenic was discovered by Bronze Age in year 1250 in unknown place. Arsenic derived its name from English word (Latin arsenicum)
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
