History
| Parameter | Oxygen | Fluorine |
|---|---|---|
| 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 Fluorine was discovered by A.-M. Ampère in year 1810 in France. Fluorine derived its name from the Latin fluere, meaning 'to flow'. |
