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 Mercury was discovered by unknown in year 1500 BC in unknown place. Mercury derived its name derived its name from from the New Latin name mercurius, named after the Roman god (Hg from former name hydrargyrum, from Greek hydr-, 'water', and argyros, 'silver')
