Palapala noi

ʻO ka Praseodymium he metala palupalu palupalu, ʻulaʻula-melemele. He lālā ia o ka pūʻulu lanthanide o ka papa manawa o nā mea. Hoʻololi mālie ʻo ia me ka oxygen: i ka wā e ʻike ʻia ai i ka ea, hana ʻo ia i ka oxide ʻōmaʻomaʻo ʻaʻole e pale iā ia mai ka hoʻoneʻe hou ʻana. ʻOi aku ka pale ʻana i ka ʻino i ka ea i nā metala ʻē aʻe, akā pono e mālama ʻia ma lalo o ka aila a i uhi ʻia me ka plastic. Hiki koke ia me ka wai.
