History
| Parameter | Phosphorus | Nitrogen |
|---|---|---|
| History | The element Phosphorus was discovered by H. Brand in year 1669 in Germany. Phosphorus derived its name from the Greek word phoosphoros, 'carrying light'. | The element Nitrogen was discovered by D. Rutherford in year 1772 in United Kingdom. Nitrogen derived its name from the Greek word nitron and '-gen' meaning 'niter-forming'. |
