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 Cobalt was discovered by Georg Brandt in year 1735 in Sweden. Cobalt derived its name derived its name from from the German word Kobold, meaning 'goblin'
