Onnesium/meta
Rancke & TJonesLow Notes (2007)[edit]
In the real universe atomic element 118 was provisionally named Ununoctium when it was first discovered, and it is highly unstable.
Notes (2016)[edit]
As of 2016, IUPAC has announced the official name of Element 118 as Oganesson (after Russian physicist Yuri Oganessian).
- Apparently 3000 years of evolution of the Anglic language has altered the morphology of the name a bit, from Oganesson to Onnesium.

Notes (2025)[edit]
Oganesson's atomic number lies just above the normative Island of Stability region. Although the current isotopes that have been produced are unstable (yet more stable than should be the case (~ 0.1 ms half-life, thus supporting the island of stability conjecture), other isotopes are predicted to last longer. The super-heavy elements suffer from relativistic distortion of their electron orbitals due to their outer electrons approaching lightspeed; this causes the periodicity of the periodic table to become skewed. Oganesson is in fact NOT a noble gas, but is a metalloid solid at STP and an electropositive semiconductor.
