Heavy Metals (f-block elements)

Heavy metals in the context of f-block elements refer to the lanthanides and actinides. These elements are characterized by their high atomic numbers, high densities, and occupation of the 4f or 5f orbitals in their electron configurations. They exhibit properties such as variable oxidation states, formation of colored ions, and a strong tendency to form complex compounds. Actinides are mostly radioactive, which presents safety and environmental concerns. While not traditionally drug targets, they interact with chelating agents in cases of toxicity and are employed as radiopharmaceuticals in cancer therapy. Lanthanides have applications in electronics, catalysts and magnets.
