History
| Parameter | Aluminium | Chlorine |
|---|---|---|
| History | The element Aluminium was discovered by H.C.Ørsted in year 1825 in Denmark. Aluminium derived its name from alumina, a compound (originally aluminum). | The element Chlorine was discovered by W. Scheele in year 1774 in Sweden. Chlorine derived its name from the Greek word chloros, meaning 'greenish yellow'. |
