History
| Parameter | Mercury | Aluminium |
|---|---|---|
| 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 Aluminium was discovered by H.C.Ørsted in year 1825 in Denmark. Aluminium derived its name from alumina, a compound (originally aluminum). |
