History
| History | 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'. | The element Strontium was discovered by W. Cruikshank in year 1787 in United Kingdom. Strontium derived its name from Strontian, a small town in Scotland. |
