The actinide /ˈæktɨnaɪd/ or actinoid /ˈæktɨnɔɪd/ (iupac nomenclature) series encompasses the 15 metallic chemical elements with atomic numbers from 89 to 103, actinium through lawrencium.[2][3][4][5].
34+ Actinide Series Examples. Members of the series are often called actinides, although study of the properties of the actinides is hampered by their radioactive instability. The series is the row below the lanthanide series, which is located underneath the main body of the periodic table.
