Abstract: Chemical bond theory is a fundamental topic in inorganic chemistry, encompassing a rich array of concepts, from classical covalent bond theory to molecular orbital theory. However, the diversity and inherent limitations of these theories often pose challenges for students, particularly in their study and comprehension. This is especially evident when analyzing compound properties, where different theories may lead to conflicting conclusions. In response to these challenges, this paper emphasizes the core principle of chemical research: the relationship between a material’s structure and its properties, commonly referred to as the “structure-activity relationship”. By introducing the Team-Based Learning (TBL) teaching method, students can develop a comprehensive understanding of chemical bond theory and enhance their ability to interpret, analyze, and solve real-world problems.
