NCERT Grade 12 Chapter 8, d and f-Block Elements deals with the elements of the d and f-block of the modern periodic table. In this chapter, students shall first deal with the electronic configuration, occurrence and general characteristics of transition elements with special emphasis on the trends in the properties of the first row (3d) transition metals along with the preparation and properties of some important compounds. This will be followed by consideration of certain general aspects such as electronic configurations, oxidation states and chemical reactivity of the inner transition metals.
After studying this chapter, students will be able to learn the positions of the d– and f-block elements in the periodic table; know the electronic configurations of the transition (d-block) and the inner transition (f-block) elements; appreciate the relative stability of various oxidation states in terms of electrode potential values; describe the preparation, properties, structures and uses of some important compounds such as K2Cr2O7 and KMnO4; understand the general characteristics of the d– and f–block elements and the general horizontal and group trends in them; describe the properties of the f-block elements and give a comparative account of the lanthanoids and actinoids with respect to their electronic configurations, oxidation states and chemical behaviour.
Position in the Periodic Table, Electronic Configurations of the d-Block Elements, General Properties of the Transition Elements (d-Block), Physical Properties, Variation in Atomic and Ionic Sizes of Transition Metals, Ionisation Enthalpies, Oxidation States, Trends in the M2+/M Standard Electrode Potentials, Trends in the M3+/M2+ Standard Electrode Potentials, Trends in Stability of Higher Oxidation States, Chemical Reactivity and E Values, Magnetic Properties, Formation of Coloured Ions, Formation of Complex Compounds, Catalytic Properties, Formation of Interstitial Compounds, Alloy Formation, Some Important Compounds of Transition Elements, Oxides and Oxoanions of Metals, The Lanthanoids, Electronic Configurations, Atomic and Ionic Sizes, Oxidation States, General Characteristics, The Actinoids, Electronic Configurations, Ionic Sizes, Oxidation States, General Characteristics and Comparison with Lanthanoids and Some Applications of d- and f-Block Elements are the topics studied in this chapter.
