Hey,
• The elements in which the last electron enters the f-orbitals of their atoms are called f-block elements.
• Lanthanoids or Lanthanides or rare earth metals: The first series follows lanthanum, La (Z= 57) and the elements present in this series from cerium to lutetium (58Ce – 71Lu) are called lanthaniods or lanthanides. These are also called rare earth elements.
• Actinoids or Actinides: The second series follows actinium, Ac (Z = 89) and the elements present in this series from thorium to lawrencium (90Th - 103Lr) are called actionoids or actinides. These are of radioactive elements.
