All of the possible electron totals shy of the superheavy elements are accounted for.
Yes, but we don't really KNOW that everything pre-superheavy is stable and everything post-superheavy isn't.See: Technetium, which has no stable isotopes and is way, way, WAY before the superheavies.
There can be more elements with already existing electron totals, just with different properties.
But we know of everything pre-superheavy, and whether or not it is stable. Plus, post-superheavy elements are extremely scarce, so I don't really see how life could be based on such a rare element.Says who?
Possibilities.
Now consider an atom in that space
it means the planets are ours to colonize and explore :)
You can try wormhole travel but in my opinion, the theory of the universe is flawed.
