NCERT Solutions for Class 12 Chemistry chapter 8 The d and f block elements

In this chapter, we will study the d-block and f-block elements and their general and physical properties. This chapter is not lengthy like chapter 7 the p-block elements but it is an important chapter because it holds 5 marks out of 70 in the CBSE Board exam. In this chapter, there are eight sub-topics which covers important concepts on d- and f-block elements and to check students knowledge 38 questions are given in the exercise at the end of the chapter. The NCERT Solutions for Class 12 Chemistry chapter 8 The d and f block elements are designed by subject experts to clear students doubts.

In NCERT Class 12 Chemistry chapter 8 The d and f block elements we will first deal with the d-block elements with their properties and then f-block elements. The d-block elements are elements of groups 3 to 12 of the periodic table. The name transition metals are often used to refer to the d-block elements. There are 4 PERIODS & 10 GROUPS in D-block and number of elements present in it is 40. The f-block consists of elements in which 4f and 5f orbitals are progressively filled. The f-block elements are placed at the bottom of the periodic table in the separate panel. The name inner-transition metals are often used to refer to the f-block elements.

In chapter 8 The d and f block elements we will first deal with the occurrence, electronic configuration and general characteristics of transition elements and discuss important trends in the properties of the first row (3d) transition metals, preparation and properties of some important compounds. After this, we will discuss oxidation states, electronic configurations and chemical reactivity of the inner transition metals
