The lanthanides and actinides are located in the f-block of the Periodic Table. The lanthanides are found in the sixth period, spanning from cerium (Ce, atomic number 58) to lutetium (Lu, atomic number 71). The actinides are in the seventh period, ranging from actinium (Ac, atomic number 89) to lawrencium (Lr, atomic number 103). Both series are typically displayed separately at the bottom of the periodic table to maintain its overall structure.
