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 Cobalt was discovered by Georg Brandt in year 1735 in Sweden. Cobalt derived its name derived its name from from the German word Kobold, meaning 'goblin' |
