Class 12 CBSE CHEMISTRY Unit: d and f block elements

The chapter on d- and f-block elements in Class 12 Chemistry focuses on their electronic configurations, oxidation states, and unique properties such as variable valency, formation of colored compounds, magnetic behavior, and catalytic activity. It covers trends in atomic/ionic radii, ionization enthalpy, and lanthanoid contraction, along with the chemical reactivity of these elements.

Learn about the industrial, biological, and catalytic uses of transition and inner transition elements.
