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 Thulium was discovered by Per Teodor Cleve in year 1879 in Sweden. Thulium derived its name derived its name from from Thule, the ancient name for Scandinavia
