History
| Parameter | Europium | Mercury |
|---|---|---|
| History | The element Europium was discovered by E.-A. Demarçay in year 1896 in France. Europium derived its name from Europe. | 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'). |
