examples of artificial elements
Answers
Answer:
not or no longer occurring on earth, but artificially generated by nuclear reaction. The artificial elements include the elements technetium (atomic number Z = 43), promethium (Z = 61) and the tran-suraniums (Z > 92). A total of 118 elements are therefore known today. In the 70’s, it could be verified that very low traces of plutonium occur in nature resulting from natural nuclear fissions (about 1 pluto-nium atom per 1012 uranium atoms).
