History
| Parameter | Gallium | Oxygen |
|---|---|---|
| History | The element Gallium was discovered by P. E. L. de Boisbaudran in year 1875 in France. Gallium derived its name from Gallia, the Latin name for France. | 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'. |
