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