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 Calcium was discovered by Humphry Davy in year 1808 in United Kingdom. Calcium derived its name derived its name from from the Latin calx, meaning 'lime'
