History
| Parameter | Thulium | Mercury |
|---|---|---|
| History | The element Thulium was discovered by T. Cleve in year 1879 in Sweden. Thulium derived its name from Thule, the ancient name for Scandinavia. | 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'). |
