Superheavy elements, also known as transactinide elements, transactinides, or super-heavy elements, or superheavies for short, are the chemical elements with atomic number greater than 104. [1] The superheavy elements are those beyond the actinides in the periodic table; the last actinide is lawrencium (atomic number 103).
Unbihexium has attracted attention among nuclear physicists, especially in early predictions targeting properties of superheavy elements, for 126 may be a magic number of protons near the center of an island of stability, leading to longer half-lives, especially for 310 Ubh or 354 Ubh which may also have magic numbers of neutrons.

Yuri Tsolakovich Oganessian [a] (born 14 April 1933) is an Armenian and Russian nuclear physicist who is best known as a researcher of superheavy chemical elements. [7] He has led the discovery of multiple elements of the periodic table.
Victor Ninov (Bulgarian: Виктор Нинов; born June 24, 1959) is a Bulgarian physicist and former researcher who worked primarily in creating superheavy elements. He is known for the co-discoveries of elements 110, 111, and 112 (darmstadtium, roentgenium and copernicium, respectively). [1]
Like the rest of the superheavy elements, the nuclides within the island of stability have never been found in nature; thus, they must be created artificially in a nuclear reaction to be studied. Scientists have not found a way to carry out such a reaction, for it is likely that new types of reactions will be needed to populate nuclei near the ...
Extinct isotopes of superheavy elements are isotopes of superheavy elements whose half-lives were too short to have lasted through the formation of the Solar System, [1] and because they are not replenished by natural processes, can nowadays only be found as their decay products (from alpha decay, cluster decay or spontaneous fission) trapped within sediment and meteorite samples dating ...

In 2014 she was an editor of the book The Chemistry of Superheavy Elements. [ 2 ] While leading the heavy element group, Shaughnessy partnered with the Joint Institute for Nuclear Research ; the team managed to identify five new superheavy elements .
