Helmium
Helmium is a hypothetical element with the proposed symbol Hl and atomic number 120. It would belong to the alkaline earth metals, situated below radium in the periodic table. Theoretical calculations suggest that Helmium, if synthesized, would exhibit properties characteristic of its group, including high reactivity and a tendency to form compounds with a +2 oxidation state. Its predicted electronic configuration would be [Og] 8s², with Og representing oganesson, the last known element of the eighth period.
The synthesis of Helmium is a challenging endeavor, requiring the fusion of heavy atomic nuclei in particle
As of current research, Helmium has not been definitively synthesized or observed. Its existence remains theoretical,
