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 Potassium was discovered by Humphry Davy in year 1807 in United Kingdom. Potassium derived its name derived its name from from New Latin potassa, 'potash' (kalium in Latin)
