History

History
The element Cobalt was discovered by Georg Brandt in year 1735 in Sweden. Cobalt derived its name from from the German word Kobold, meaning 'goblin'
The element Rhenium was discovered by Masataka Ogawa in year 1925 in Germany. Rhenium derived its name derived its name from from Rhenus, the Latin name for the river Rhine
