Chapter 8 - The D And F Block Elements

The D and F Block Elements Class 12 NCERT Solutions, is one of the most important topics in the Chemistry book of the CBSE curriculum. Also known as transition elements and inner elements, respectively, the D and F Block Elements are in groups of 3 to 11 in the periodic table. The 4f and 5f orbitals of f-block elements are steadily in later of two long periods. Based on this they are differentiated in lanthanides and actinides. The D Block Elements, which are transition elements have partially filled (n-1) d-orbitals. We can get to know about the properties and nature of an element in the periodic table based on its position in the same. Therefore, to understand why a certain element falls under the D Block or the F Block we need to know which elements lie in which group position in the periodic table. The D Block and the F Block elements have certain properties, which make them fall under this category. You will study more about this in detail in Chapter 8 D and F Block NCERT Solutions.

In Class 12 Chemistry Class 12 NCERT Solutions Chapter 8 you will learn - 

In Chemistry Class 12 NCERT Solutions Chapter 8 you will learn about the D Block Elements which consists of groups 3 to 12 in the periodic table and the F Block Elements which are placed outside at the bottom of the periodic table. The D Block Elements progressively fill the inner d orbitals, and the elements in the F Block fill the 4f and 5f orbitals. Known also as transition elements, these elements exhibit metallic properties as they are high tensile strength, ductility, malleability, thermal and electrical conductivity and are metallic in character. For more detailed explanations of the topics in this chapter, refer to D and F Block Elements Class 12 NCERT Solutions PDF and other materials online.
