The D- and F-block elements are elements in which the differentiating electron enters the d or f orbital, respectively. D-block elements are called transition elements, while f-block elements include lanthanoids and actinoids. These elements show variable oxidation states, coloured ions, and complex formation.

Chemical Kinetics – Class 12 Chemistry Chemical Kinetics is the branch of chemistry that deals with the rate of chemical reactions, factors affecting reaction rates, order and molecularity of reactions, rate laws, activation energy, and the Arrhenius equation. It helps us understand how quickly reactions occur.
