History

History
The element Argon was discovered by Lord Rayleigh in year 1894 in United Kingdom. Argon derived its name from from the Greek word argos, meaning 'idle'
The element Praseodymium was discovered by Carl Auer von Welsbach in year 1885 in Austria. Praseodymium derived its name derived its name from from the Greek praseios didymos meaning 'green twin'
