Hint: According to IUPAC, an element exists if its lifetime is longer than ${10^{ - 4}}$ seconds that is the time taken for the nucleus for the formation of an electron cloud. The naming of the superheavy element is after the chemists, physicists, or on the location involved in the synthesis.

Complete Step By Step Answer:
Trans actinide elements or transactinides are also called superheavy elements.
Superheavy elements are the elements that have a large number of protons in their nucleus. The superheavy element usually does not occur naturally on earth in large quantities as elements with more than 92 protons are not stable, with a characteristic half-life it can exist under highly controlled conditions.
Superheavy elements refer to the element with an atomic number greater than 103 and they are usually radioactive elements.
In the periodic table, the known superheavy elements form constituents of the 6d and 7p series.
Relativistic effect (can be considered to be perturbations, to the non-relativistic theory of chemistry, developed from the solutions of Schrödinger equation.) because the empty 7p orbitals, filled 7s orbital and filled 6d orbital to contract inwards towards the atomic nucleus, due to this relativistic stabilization of 7s electrons taking place makes the 7p orbitals attainable in low excitation states.

Note:
When two nuclei of unequal size combine into one in a nuclear reaction a superheavy atomic nucleus is created. Fusion of the two nuclei into one happens if they proceed towards each other closely enough (but usually nuclei due to electrostatic repulsion, they repel each other) this repulsion can be conquered by strong interaction but within a very short distance from the nucleus.
