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 Argon was discovered by Lord Rayleigh and W. Ramsay in year 1894 in United Kingdom. Argon derived its name from the Greek word argos, meaning 'idle'.
