Radonia

Radonia is a fictional chemical element and, in some science fiction contexts, a mineral name. It is not a real element recognized by IUPAC or any scientific database. The term is used across multiple works to denote an exotic, high-energy material.

In typical depictions, radonia is a heavy, highly unstable material with large energy density. It may be described as radioluminescent, emitting a blue or violet glow, and its chemistry is often simplified for storytelling. Some authors give it multiple allotropes or crystalline forms, while others treat it as a single, irregular phase. Handling is dangerous, requiring specialized shielding.

Source and mining: In fictional worlds, radonia is found in meteorites, deep lunar craters, asteroid belts, or rare veins within planets. Extraction is costly and technologically demanding, with environmental or political tensions around ownership.

Uses and significance: Radonia is commonly portrayed as a power source for propulsion systems, reactors, or weapons. It can enable near-future or far-future technologies, or serve as a catalyst in exotic chemistry. The material's scarcity often drives plot conflict and exploration.

Note: The term is entirely fictional; occasional crossovers in fan works may reuse or repurpose the name. Real-world minerals or elements with similar-sounding names, such as radon, are unrelated to radonia.
