History
| Parameter | Mercury | Tellurium |
|---|---|---|
| History | The element Mercury was discovered by Indians/Chinese in year Before 2000 BCE. Mercury derived its name 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 Tellurium was discovered by F.-J.M. von Reichenstein in year 1782 in Romania. Tellurium derived its name from Latin tellus, meaning 'earth'. |
