[PAR] [TLE] Actinide [SEP] The actinide or actinoid (IUPAC nomenclature) series encompasses the 15 metallic chemical elements with atomic numbers from 89 to 103, actinium through lawrencium. [PAR] [TLE] Core electron [SEP] Core electrons are the electrons in an atom that are not valence electrons and therefore do not participate in bonding.  The number of valence electrons of an element can be determined by the periodic table group of the element.  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.  All the non-valence electrons for an atom of that element are considered core electrons.
