Answer:

The f block elements are the lanthanides and actinides and are called the inner transition elements because of their placement in the periodic table due to their electron configurations. The f orbitals of the electron shell are filled with “n-2.” There is a maximum of fourteen electrons that can occupy the f orbitals.

These f-block elements are placed at the bottom of the periodic table in two rows . They are 4f series and 5f series . As the properties of 4f series elements are similar to Lanthanum , they are known as Lanthanide (or) Lanthanons or rare earths 5f-series elements- Actinide series - configuration 5f¹-¹⁴ 6d⁰-¹ 7s² from Th (90) to Lr (103) (second inner transitional series) . It belongs to 7 th period and 3rd B group. In this most of the elements are radioactive and they have properties similar to D-block elements . Differentiating electrons enter into f-subshell of anti penultimate i.e.,( n-2) shell
