Periodic Trends and Chemical Bonding: Foundational Concepts and Practice

Chemistry starts with understanding how atoms interact. This course provides the foundational knowledge needed to master the periodic table and the forces that bind atoms together. By the end of this course, you will be able to predict chemical properties based on an element's position, interpret various types of chemical bonds, and systematically approach common problem types related to structure and reactivity. What you'll learn: * Understand the organization of the modern periodic table and the significance of quantum numbers in defining electron configuration. * Analyze key periodic trends, including ionization energy, electron affinity, and atomic radius, and explain exceptions to these trends. * Master the formation and properties of ionic, covalent, and metallic bonds using electronegativity differences and Lewis structures. * Apply Valence Shell Electron Pair Repulsion (VSEPR) theory to predict the molecular geometry and polarity of common simple molecules. * Practice solving quantitative problems involving bond energy, lattice enthalpy, and formal charges. The course begins by establishing the principles of atomic structure and electron arrangement, then systematically moves through major periodic trends. The second half focuses entirely on the mechanisms and representations of chemical bonding, concluding with extensive problem-solving practice. This course is designed for absolute beginners in chemistry or those needing a strong foundation refresh. No prior advanced chemistry knowledge is required to start.
