Codsiga

Praseodymium waa bir jilicsan oo jilicsan, jaalle- silvery. Waa xubin ka mid ah kooxda lanthanide ee shaxda xilliyeed ee curiyeyaasha. Waxay si tartiib ah ula falgashaa ogsijiin: marka ay hawada soo gasho waxay samaysaa oksaydh cagaaran oo aan ka ilaalinayn oksijiinta dheeraad ah. Waxay aad ugu adkaysataa daxalka hawada biraha kale ee naadirka ah, laakiin wali waxay u baahan tahay in lagu kaydiyo saliid hoosteeda ama lagu daboolo balaastig ah. Waxay si degdeg ah ula falgashaa biyo.
