Which are the transition elements and inner transition elements ?

1.	Which are the transition elements and inner transition elements ?
Answer» Solution :3d transition element : Sc (Z = 21) to Zn (Z = 30) 4d transition element: Y (Z = 39) to Cd (Z = 48) 5d transition element: La (Z = 57) to HG (Z = 80) 6d transition element: Ac (Z = 89) to Cn (Z = 112) 4F inner transition elements or Lanthanoid series : Ce (Z = 58) to Lu (Z = 71) 5finner transition elements or ACTINOID series: Th (Z = 90) to Lr (Z = 103)
