Aside from the series that ranges from atomic numbers 89 to 103, what series is an exception to the rule that the number of valence electrons ranges from 0-8 electrons?
Core electron:  With the exception of the transition metals in groups 3-12 and the Lanthanide and Actinide series, the number of valence electrons ranges from 0-8 electrons. Actinide: The actinide or actinoid (IUPAC nomenclature) series encompasses the 15 metallic chemical elements with atomic numbers from 89 to 103, actinium through lawrencium.
Lanthanide
