These are actinides other than uranium and plutonium and include neptunium, americium and curium. Berkelium was the fifth transuranium element discovered after neptunium, plutonium, curium and americium. Seaborg developed the chemical elements americium and curium while in Chicago. Other fission products remain in the aqueous phase, including americium and curium. Further separation was carried out by ion exchange, yielding a certain isotope of curium. There are exceptions, however, including several isotopes of curium and dubnium. Lv and Lv could be accomplished by fusing the heavy curium isotope curium-250 with calcium-48. The element with atomic number 96 was named curium. Curium (Cm) is an artificial element with an atomic number of 96. Metallic curium is obtained by reduction of its compounds. Therefore, this application of curium is currently considered impractical. The city of Limassol is situated between the ancient cities of Amathus and Kourion (Curium).
