ABSTRACT
Recently, there has been discussion in the literature
about two new sets of values that have been predicted
via theory for the electron affinities of the lanthanide
elements. In addition, there have been new theoretical
predictions of values for the actinide elements.
In this paper, we use these new values to explore the
scaling of quantum capacitances for lanthanide and actinide
atoms as a function of mean radii for their outermost
occupied orbitals. In the process, we analyze
from a capacitance-based perspective, across the entire
row of the perodic table, the two differing sets of predictions
for the electron affinities of lanthanide atoms.
