Element, artificial
 scroll 
Element 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).
