Hello, I’m Avinto, your guide to understanding Complex Formation in transition elements! Transition metals often form complexes with molecules or ions called ligands. These complexes are central to many chemical reactions, including catalysis and bioinorganic processes. Together, we’ll explore the factors that favor complex ion formation, types of ligands, and how to name complexes using the IUPAC system. We’ll also cover the geometry of common complexes, like tetrahedral and octahedral shapes.
