Actually the real fun should begin somewhere around atomic number 137.
That's where Quantum Electrodynamic effects (spontaneous production
of electon-positron pairs and suchlike) should start to appear. (The
smallness parameter for QED is the fine-structure constant, \alpha
~1/137, so multiplying by a nuclear charge of 137 brings these up to
order 1.) A species that can pull an electron out of the _vacuum_
has gotta count as one hell of a Lewis acid!
