Isicelo

I-Praseodymium iyinsimbi ethambile ethambile, ephuzi-ephuzi. Iyilungu leqembu le-lanthanide lethebula le-periodic lama-elementi. Isabela kancane ne-oxygen: lapho ivulekele emoyeni yenza i-oxide eluhlaza engayivikeli ekuqhubekeleni phambili kwe-oxidation. Iyakwazi ukumelana nokugqwala emoyeni ezinye izinsimbi ezingavamile, kodwa isadinga ukugcinwa ngaphansi kwamafutha noma imbozwe ngepulasitiki. Isabela ngokushesha emanzini.
