History
| Parameter | Oxygen | Phosphorus |
|---|---|---|
| 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 Phosphorus was discovered by H. Brand in year 1669 in Germany. Phosphorus derived its name from the Greek word phoosphoros, 'carrying light'. |
