History
| Parameter | Oxygen | Aluminium |
|---|---|---|
| History | The element Oxygen was discovered by W. Scheele in year 1771 in Sweden and United Kingdom. Oxygen derived its name from the Greek word oxy-, both 'sharp' and 'acid', and -gen, meaning 'acid-forming'. | The element Aluminium was discovered by H.C.Ørsted in year 1825 in Denmark. Aluminium derived its name from alumina, a compound (originally aluminum). |
