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.
