How are heavy elements created
WebMost superheavy elements are very unstable and it is unlikely that scientists will ever make one that sticks around for more than even a few minutes. However, since the 1960s, scientists have predicted that some superheavy isotopes would have half-lives several orders of magnitude longer than others. This is the island of stability.
