Fundamentals of Atomic and Molecular Structure

Chemistry and physics rely fundamentally on understanding how atoms are built and how they interact; this course provides the essential framework for visualizing the microscopic world. By the end of this course, you will master the modern quantum mechanical model of the atom, confidently interpret quantum numbers, and predict molecular geometry and properties using established bonding theories. What you'll learn: Understand the evolution from classical atomic models to the modern quantum mechanical description of matter. Master the four quantum numbers and apply the Pauli Exclusion Principle and Hund's Rule to determine electron configurations. Apply Valence Shell Electron Pair Repulsion (VSEPR) theory to accurately predict three-dimensional molecular shapes and polarity. Analyze chemical bonding using both Valence Bond Theory (VBT) and Molecular Orbital Theory (MOT) for diatomic molecules. Configure electron distributions in multi-electron atoms and predict fundamental periodic trends. Practice interpreting basic molecular symmetry elements crucial for advanced chemical analysis. This text-only course begins with the foundational principles of quantum mechanics, progresses through atomic structure and electron configuration, and culminates in a detailed examination of chemical bonding and molecular geometry. This course is designed for absolute beginners with no prior experience in quantum chemistry or advanced physics; all necessary concepts are introduced clearly and sequentially.
