Praseodymium nicyuma cyoroshye, cyuma-umuhondo. Numunyamuryango witsinda rya lanthanide yimbonerahamwe yigihe cyibintu. Ifata buhoro buhoro hamwe na ogisijeni: iyo ihuye nikirere ikora oxyde yicyatsi itayirinda okiside. Irwanya cyane kwangirika mu kirere ibindi byuma bidasanzwe, ariko biracyakenewe kubikwa munsi yamavuta cyangwa bigashyirwaho plastike. Ifata vuba n'amazi.
