Organokupari
Organokupari is a hypothetical element with the symbol Ok and atomic number 120. It is predicted to be an alkaline earth metal and the next element in the periodic table after unbinilium (element 120). As a superheavy element, organokupari would be highly unstable and radioactive, with a very short half-life. Its chemical properties are expected to resemble those of other alkaline earth metals, such as barium and radium, though relativistic effects might lead to some deviations. Theoretical calculations suggest that organokupari might be more volatile than lighter alkaline earth metals. Due to its extreme instability, organokupari has not yet been synthesized or observed. Its existence and properties remain in the realm of theoretical predictions based on nuclear physics models. The study of such superheavy elements is crucial for understanding the limits of nuclear stability and the behavior of matter under extreme conditions. Future research aims to synthesize elements beyond the current known range, which could include organokupari.
