heliumumpe

Heliumumpe is a hypothetical element with the atomic number 120. As a superheavy element, it would be located in the eighth period of the periodic table, in group 2, making it an alkaline earth metal. Theoretical calculations suggest that heliumumpe would be a solid at room temperature and pressure. Its electron configuration is predicted to end in 8s², placing it below radium in the periodic table.

The synthesis of element 120 has been attempted by several research groups, but it has not yet been officially confirmed or discovered. These experiments typically involve the fusion of heavy nuclei. For instance, bombarding a curium target with a titanium beam or a californium target with a chromium beam are among the proposed reaction pathways. The extreme instability of superheavy elements means that even if synthesized, heliumumpe would likely have a very short half-life, decaying rapidly into lighter elements.

The existence and properties of heliumumpe are primarily theoretical, based on extrapolations of periodic trends and nuclear physics models. Its chemical properties are expected to resemble those of other alkaline earth metals, such as barium and radium, though relativistic effects may lead to some deviations. The study of such superheavy elements is crucial for understanding the limits of nuclear stability and the structure of the periodic table.
