kaliumionia

Kaliumionia is a hypothetical chemical element with the symbol Ki and atomic number 121. It is predicted to be the first element in the g-block of the periodic table and the first superactinide. As such, its chemical properties are largely unknown and extrapolated based on theoretical models. Due to its extremely high atomic number, kaliumionia is expected to be highly unstable and radioactive, with a very short half-life.

Theoretical calculations suggest that kaliumionia would be a metal, likely with a solid state at room temperature. Its electron configuration is predicted to be [Og] 8s² 5g¹, though the precise orbital filling is a subject of ongoing theoretical study. The g-block elements, to which kaliumionia would belong, are characterized by the filling of the g-orbital. The properties of these elements are expected to diverge significantly from those of lighter elements, as relativistic effects become more pronounced.

The synthesis of kaliumionia, if achievable, would likely involve high-energy nuclear fusion reactions. The creation and detection of such superheavy elements are extremely challenging, requiring sophisticated experimental techniques. Even if synthesized, the minuscule quantities produced and their rapid decay would make detailed chemical investigation exceedingly difficult. Kaliumionia remains a theoretical construct, its existence and properties awaiting potential experimental confirmation.
