The consequences of having an element with an atomic number above 137 would have significant implications for the structure and behavior of matter. According to current scientific understanding, an atomic number above 137 would surpass the theoretical limit for the stability of atomic nuclei in the framework of the quantum theory of electrons and the electromagnetic force.
This theoretical limit, known as the "island of stability," suggests that elements with atomic numbers significantly higher than 137 would have extremely short half-lives, making them highly unstable and difficult to observe or study under normal conditions. The island of stability proposes that there may be a region of relatively stable superheavy elements beyond the current periodic table, but the specific properties of such elements and the exact location of this region are still subjects of ongoing research and speculation.
It's important to note that no elements with atomic numbers above 118 (oganesson) have been successfully synthesized or observed. Thus, the consequences of elements with atomic numbers above 137 remain speculative and theoretical at this point. Further advancements in scientific understanding and experimental techniques are necessary to explore the possibilities in this realm.
