Element Story - 137

The element with atomic number 137 has not yet been discovered or officially confirmed, so it has no name or official designation. Therefore, the current periodic table is confirmed up to Oganesson, atomic number 118. However, research to synthesize superheavy elements beyond 119 is ongoing theoretically, and the number 137 is of particular interest from the perspective of atomic structure and relativistic quantum mechanics. If the Bohr model were applied simplistically, as the atomic number approaches 137, the speed of the innermost electrons would approach the speed of light. Since actual atoms must be described by the Dirac equation and quantum electrodynamics, it cannot be definitively stated that an atom cannot exist at 137. However, for very large atomic numbers, strong relativistic effects and the quantum nature of the vacuum are expected to significantly influence atomic structure. To date, the actual physical and chemical properties of element 137 are unknown, and its possibility of existence is also a subject of theoretical research.
