what are their early predictions ?
In 1914, German physicist Richard Swinne proposed that elements heavier than uranium, such as those around "Z" = 108, could be found in cosmic rays
Superheavy element

where are the most massive elements on the periodic table UNANSWERABLE what is the island of stability ? In nuclear physics, the island of stability is a predicted set of isotopes of superheavy elements that may have considerably longer half-lives than known isotopes of these elements. who discovered it ? UNANSWERABLE what are super heavy elements you mentioned above ? Superheavy elements, also known as transactinide elements, transactinides, or super-heavy elements, are the chemical elements with atomic numbers greater than 103. who discovered them ? Glenn T. Seaborg first proposed the actinide concept, which led to the acceptance of the actinide series. what are their characteristics ? Due to their short half-lives (for example, the most stable known isotope of seaborgium has a half-life of 14 minutes, and half-lives decrease gradually going to the right of the group) and the low yield of the nuclear reactions that produce them

Superheavy element [SEP] Early predictions
Swinne published these predictions in 1926, believing that such elements might exist in the Earth's core, in iron meteorites, or in the ice caps of Greenland where they had been locked up from their supposed cosmic origin.
