Dübelelement

Dübelelement is a hypothetical chemical element referenced in theoretical chemistry and in certain science fiction contexts. In these discussions it is assigned the symbol Du and is sometimes placed in the early part of the superheavy region of the periodic table, with atomic number commonly proposed as 122. The name derives from the German word dübel, meaning dowel or anchor, reflecting its imagined role as a mechanically robust component in advanced materials.

Predicted properties from theoretical models include a high atomic mass and density, as well as a high melting point. The element is expected to form metallic or covalent networks with several possible oxidation states, often cited as +4 or +6 in oxides. The electronic structure is described in speculative calculations as contributing to unusual stability in certain lattice environments, though this remains unverified.

Occurrence and synthesis: There is no experimental evidence for Dübelelement. In speculative scenarios, it could only be produced in extreme nuclear- fusion experiments that create very short-lived isotopes, with half-lives ranging from milliseconds to seconds, making direct observation challenging.

Applications and significance: In materials science simulations, Dübelelement serves as a theoretical benchmark for exploring extreme-strength alloys and anchoring components. In practice, its existence is unproven, and it remains a fictional or hypothetical construct used to illustrate ideas about extended periodic tables and superheavy chemistry.
