Superheavy-element compound reveals weaker-than-expected bond due to relativistic effects
Researchers have measured the chemical stability of a seaborgium compound, finding that its bonds are weaker than expected due to relativistic effects. This study provides new insights into how high nuclear charges influence the electronic structure of superheavy elements.
Why it matters
Understanding relativistic effects in superheavy elements advances fundamental knowledge of atomic physics and the periodic table.

Yakushev An international collaboration led by a research group from GSI/FAIR in Darmstadt, Germany, has achieved the first measurement of the chemical stability of a superheavy element compound.
The focus was on the hexacarbonyl complex Sg(CO)₆ of seaborgium (Sg, element 106). The result: The bond between the seaborgium atom and a carbonyl ligand is weaker than expected based on its position in the periodic table. Relativistic effects are the cause.
The results are published in the journal Nature .
