History

History
The element Beryllium was discovered by Louis Nicolas Vauquelin in year 1797 in France. Beryllium derived its name from from beryl, a mineral
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'
