Dinosaur said:There was an interesting SciFi story about the development of element 120.
In the story, element 120 was the start of a series of elements which were the reverse of unstable. Once synthesized, element 120 absorbed protons & neutrons from its enviroment and became element 121. 121 behaved similarly. The series of reactions continued until element 240 was created. element 240 split into two atoms of element 120.
