Koalíónum

Koalíónum is a fictional chemical element introduced in speculative science fiction. In the canonical lore, it is a heavy metallic element with a high atomic number, noted for extreme density, mechanical strength, and unusual electronic properties.

Etymology and naming: The name combines "Koala" with the suffix -íónum, a nod to the animal as a symbol of resilience and to conventional element naming. Some sources assign the symbol Ko and consider it a transuranic element in its universe.

Discovery: Koalíónum was first proposed by researchers at Asterion Labs in 2149 and described as present in extraterrestrial ore aboard asteroids in the Koalí region. Synthesis in fiction occurs via multi-step transmutation in a high-energy collider.

Properties and compounds: It is described as highly dense, with strong corrosion and radiation resistance. It conducts electricity well and can form stable alloys with light elements. Some narratives place cryogenic superconducting-like behavior under specific conditions.

Applications and safety: Within its fictional setting, Koalíónum underpins compact superconductors, spacecraft armor, and high-density energy storage. Handling requires heavy containment due to radiological hazards, and ethics debates surround dual-use technology.
