Inner transition elements are the elements in which the last electron enters in the f-orbital. They generally belong to group 3 in the periodic table but are mentioned separately as the f block elements. These f block elements are known as inner transition elements. There are two series of inner transition elements-
In this article, we will study the main characteristics of inner transition elements. Also, the difference and similarities between lanthanoids and actinoids. Main Characteristics of Inner Transition ElementsLanthanoids: (Atomic number: 58 to 71)
Actinoids: (Atomic number: 90 to 103)
Electronic Configuration:Lanthanoids: 4f1-145p65d0-16s2 {from cerium(Z=53) to Lutetium(Z=71)} Actinoids: 5f1-146s26p66d0-17s2 {from thorium (Z = 90) to lawrencium (Z = 103)}. Similarities Between Lanthanoids and ActinoidsThe filling of the last electron to 4f orbital, the element said to belong to the first series of transition elements. 14 elements are there in the lanthanoid series after the lanthanum. As they occur immediately after lanthanum in the periodic table, these are called lanthanides or lanthanoids. Although lanthanum does not have any 4f electrons, since lanthanum closely resembles lanthanoids, it is commonly included in lanthanide. Actinides or actinides are the electrons obtained upon successive filling of 5f orbitals. They are named so because they appear in the periodic table immediately after actinium (Ac). Fourteen elements from Th(90) to Lw(103) form the sequence of actinides and are also known as the second series of inner transitions. Since actinium (Z=89) has no 5f electrons, the analysis of actinium with actinoids is customary. Distinguish Between Lanthanoids and ActinoidsSome difference between lanthanoids and actinoids are listed below-
Applications of Inner Transition Elements:
Do You Know?According to Lenntech, thorium is almost as plentiful as lead and at least three times as plentiful as uranium. According to Chemicool, the concentration of thorium in the Earth's crust is 6 parts per million by mass. Thorium is the 41st most common element in the Earth's crust, according to the Periodic Table.

Where are inner transition metals?The inner transition metals are found in the f-block, usually put at the bottom of the Periodic Table. These elements were sometimes called rare earth metals due to their extremely low natural occurrence.
What are the two inner transition metals?The lanthanides and the actinides at the bottom of the table are sometimes known as the inner transition metals because they have atomic numbers that fall between the first and second elements in the last two rows of the transition metals.
Is iron a inner transition element?Transition metals are in the d-block and have valence electrons in the d-orbital's. They can form multiple oxidation states and form different ions. Iron, Cobalt and Nickel are ferromagnetic. Inner transition metals are in the f-block and have valence electrons in the f-orbital's.
