History

History
The element Cadmium was discovered by Karl Samuel Leberecht Hermann in year 1817 in Germany. Cadmium derived its name from from the New Latin cadmia, from King Kadmos
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')
