Praseodymium isimbi yakapfava, ine sirivha-yellow. Iyo inhengo yeboka relanthanide yeperiodic tafura yezvinhu. Inopindirana zvishoma nezvishoma neoxygen: kana yaiswa kumhepo inoumba green oxide isingaidzivirire kubva kune imwezve oxidation. Iyo inoshingirira mukuora mumhepo mamwe masimbi asingawanzo, asi ichiri kuda kuchengetwa pasi pemafuta kana kuputirwa nepurasitiki. Inoita nekukurumidza nemvura.
