UNANSWERABLE
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 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 [SEP] Early predictions
The heaviest element known at the end of the 19th century was uranium, with an atomic mass of approximately 240 (now known to be 238) amu. Accordingly, it was placed in the last row of the periodic table; this fueled speculation about the possible existence of elements heavier than uranium and why "A" = 240 seemed to be the limit. Following the discovery of the noble gases, beginning with that of argon in 1895, the possibility of heavier members of the group was considered. Danish chemist Julius Thomsen proposed in 1895 the existence of a sixth noble gas with "Z" = 86, "A" = 212 and a seventh with "Z" = 118, "A" = 292, the last closing a 32-element period containing thorium and uranium.
