Superheavy Elements: Although elements heavier than uranium are increasingly unstable and radioactive (with half-lives measured in fractions of a second), quantum theory predicts an "island of stability," consisting of the elements with atomic numbers 114 to 122, which have half-lives measured in the millions of years. These superheavy elements, also called eka-metals or island metals. are generated in small amounts in supernova explosions. Only a few grams have ever been discovered in nature, which is just enough for scientists to determine that superheavies would be immensely valuable to industry if a source could be found. -ld IE
