History
Parameter | Antimony | Praseodymium |
---|---|---|
History | The element Antimony was discovered by Arabic alchemist in year ca. 800 AD in one. Antimony derived its name from the Greek anti, 'against', and monos, 'alone' (stibium in Latin). | The element Praseodymium was discovered by C. A. von Welsbach in year 1885 in Austria. Praseodymium derived its name from the Greek praseios didymos meaning 'green twin'. |
