Is There a Maximum Z for an Atom? - Physics Department, Princeton
... Independent of the issue of whether nuclei can exist with Zα > ∼ 1, atoms with such nuclei could not be regarded as stable, in that they could interact with their accompanying positron(s) and change their state (at least temporarily). However, since there are no longlived nuclei with Z > ∼ 100, this ...
