History

History
The element Nitrogen was discovered by Daniel Rutherford in year 1772 in United Kingdom. Nitrogen derived its name from from the Greek word nitron and '-gen' meaning 'niter-forming'
The element Helium was discovered by Pierre Janssen in year 1895 in Sweden and United Kingdom. Helium derived its name derived its name from from the Greek word helios, meaning 'sun'
