Curiyayaasha dhulka naadirka ah waxaa ka mid ahlanthanum(La),cerium(C),praseodymium(Pr),neodymium(Nd), promethium (Pm),samaroon(Sm),europium(Eu),gadolinium(Gd),terbium(Tb),dysprosium(Dy),holmium(Ho),erbium(Er),thulium(Tm),ytterbium(Yb),lutium(Lu),scandium(Sc), iyoyttrium(Y). Magaca Ingiriisigu waaDhulka naadir.Dhulka naadirbiraha guud ahaan waa jilicsan yihiin, maroojin karo, iyo ductile, waxayna muujiyaan firfircooni gaar ah oo xoog leh sida budada heerkulka sare leh. Kooxdan biraha ah waxay leeyihiin firfircooni kiimiko oo aad u xoog badan waxayna leeyihiin xidhiidh adag oo loogu talagalay hydrogen, carbon, nitrogen, oxygen, sulfur, fosfooraska, iyo halogens. Waxay si fudud hawada ugu oksaydhaysan yihiin, oo culus yihiindhul dhif ahwaxay samayn kartaa lakabka ilaalinta oksaydhka ee dusha sare eescandiumiyoyttriumheerkulka qolka. Sidaa darteed,Biraha dhulka dhifka ahGuud ahaan waxa lagu kaydiyaa kerosene ama weelal xidhan oo ay ka buuxaan vacuum iyo gaaska argon.Dhul naadir ahcuriyayaasha waxa loo qaybin karaa laba qaybood: iftiindhul dhif ahoo culusdhul dhif ah, inta badan jira qaab ahoksaydhyada dhulka naadir.
