Periodic Trends: Mastering Atomic Structure and Chemical Properties

Understanding how elements behave requires a deep knowledge of the Periodic Table's structure and the forces at play within atoms. This course provides a rigorous, foundational understanding of atomic structure and periodicity, equipping you with the analytical tools necessary to tackle complex chemical problems. What you'll learn: * Understand the modern organization of the Periodic Table based on electron configuration and quantum numbers. * Analyze and calculate effective nuclear charge and its influence on atomic size and stability. * Master the trends of ionization enthalpy, electron affinity, and electronegativity across periods and groups. * Apply the concept of the shielding effect and discuss property irregularities like the Lanthanide contraction. * Practice predicting the acidic and basic nature of oxides and hydroxides based on location in the table. * Build a framework for explaining chemical reactivity solely based on periodic position. The course begins by establishing the quantum mechanical basis for atomic structure before defining and analyzing the major periodic properties. It then moves to applying these concepts to predict chemical reactivity and property irregularities through written exercises. This course is designed for absolute beginners in chemistry or students needing a robust, college-level foundation in periodicity. No prior advanced knowledge is required.
