'''Praseodimij''' je [[1885.]] godine otkrio Carl F. Auer von Welsbach ([[Austrija]]). Ime je dobio od grčkih riječi ''prasios'' i ''didymos'' što znači zeleni blizanac. To je mekani, srebrnasti metal koji se može kovati. Na zraku se prekrije zelenom oksidnom prevlakom. Lako se otapa u vodi i kiselinama. Kada se zagrije, zapali se i izgara u Pr2O3.<br />
