History

History
The element Mercury was discovered by unknown in year 1500 BC in unknown place. Mercury 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')
The element Molybdenum was discovered by Carl Wilhelm Scheele in year 1781 in Sweden. Molybdenum derived its name derived its name from from the Greek word molybdos meaning 'lead'
