List of Elements Belonging to the Actinide Group

List of Elements Belonging to the Actinide Group The actinide or actinoid elements are a series of elements including atomic number 89 (actinium) through 103 (lawrencium). Here is a list of elements that are actinides, a subset of the rare earth elements group. Discussions of actinide elements may refer to any member of the group by the symbol An. All of the elements are f-block elements, except sometimes actinium and lawrencium. As such, the actinides are a subset of the transition metals group. Here is a list of all of the elements in the actinide series: Actinium (sometimes considered a transition metal  yet not an actinide)ThoriumProtactiniumUraniumNeptuniumPlutoniumAmericiumCuriumBerkeliumCaliforniumEinsteiniumFermiumMendeleviumNobeliumLawrencium  (sometimes considered a transition metal yet not an actinide) For more information about the actinide element group: Actinides Element Group
