History

History
The element Neodymium was discovered by Carl Auer von Welsbach in year 1885 in Austria. Neodymium derived its name from from the Greek neos didymos meaning 'new twin'
The element Curium was discovered by Glenn T. Seaborg in year 1944 in United States. Curium derived its name derived its name from from Pierre Curie, a physicist, and Marie Curie, a physicist and chemist, named after great scientists by analogy with gadolinium
