History

History
The element Fermium was discovered by Lawrence Berkeley National Laboratory in year 1952 in United States. Fermium derived its name from from Enrico Fermi, physicist
The element Neodymium was discovered by Carl Auer von Welsbach in year 1885 in Austria. Neodymium derived its name derived its name from from the Greek neos didymos meaning 'new twin'
