In the current periodic table, elements beyond uranium (atomic number of 92) are increasingly unstable and decay rapidly into other elements. Nuclear physicists theorize that an “island of stability” exists beyond the current periodic table where new superheavy elements would exhibit longer lifetimes. how do elk survive the winterA superheavy atomic nucleus is created in a nuclear reaction that combines two other nuclei of unequal size into one; roughly, the more unequal the two nuclei in terms of mass, the greater the possibility that the two react.
