History
Name | Calcium | Nitrogen |
History | The element Calcium was discovered by H. Davy in year 1808 in United Kingdom. Calcium derived its name from the Latin calx, meaning 'lime'. | 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'. |
