Chemistry Revision Notes for Class 12 Chapter 8 the D- and F-block Elements

Chapter 8 The d- and f-block Elements talks about electronic configuration, structure, properties and so on. The members present between s- and p block elements are called d-block elements. Therefore d-Block elements have intermediate properties of s-block and p-block elements:

  • They are less electropositive when compared to s-block elements
  • They are more electropositive when compared to the p-block elements
  • They are also known as transition elements

The f-block elements are also known as inner transition elements. There are total fourteen members arranged in two series namely lanthanides and actinides.

To learn more about the electronic configuration, characteristics, structure, properties, chemical behavior and more, check out the Revision Notes for Chapter 8 – The d- and f-block Elements.

Frequently asked Questions on CBSE Class 12 Chemistry Notes Chapter 6: d and f Block Elements

What are the d-block elements?

D block elements are the elements that can be found from the third group to the twelfth group of the modern periodic table. The valence electrons of these elements fall under the d orbital. D block elements are also referred to as transition elements or transition metals.

What are the f-block elements?

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.

What is the electronic configuration of f-block elements?

The general electronic configuration of 5f-block elements or actinides is [Rn] 5f0, 2 to 14 6d0,1,2 7s2.
