History

History
The element Barium was discovered by Carl Wilhelm Scheele in year 1808 in United Kingdom. Barium derived its name from from the Greek barys, meaning 'heavy'
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
