History
| Parameter | Oxygen | Sodium |
|---|---|---|
| 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 Sodium was discovered by H. Davy in year 1807 in United Kingdom. Sodium derived its name from the English word soda (natrium in Latin). |
