NCERT Class 12 Chemistry Chapter 4 The d and f Block Elements PDF Download
Chapter Overview
The d and f Block Elements is Chapter 4 of NCERT Class 12 Chemistry and deals with the properties, electronic configurations, and chemical behavior of transition and inner transition elements. The chapter explains the general characteristics of d-block elements, including variable oxidation states, colour, magnetic properties, catalytic activity, and complex formation. It also covers important compounds and reactions of transition elements, along with the properties of lanthanoids and actinoids. Students also learn about lanthanoid contraction, its consequences, and the comparison between lanthanoids and actinoids.
