Foundational Chemistry: Atomic Theory and Electron Configurations

Mastering foundational chemistry starts with a clear understanding of atomic theory and subatomic structure. This written course provides a step-by-step approach to the fundamental principles of chemistry required for standardized exams and introductory coursework. You will develop a solid grasp of atomic behavior, allowing you to solve theoretical problems and construct electronic structures with confidence. What you'll learn: - Define core terms including isotopes, atomic mass, subatomic particles, and atomic orbitals. - Explain electron energy levels and orbital geometry in clear, accessible text. - Apply Hund's rule, the Aufbau principle, and Pauli exclusion principle to write electron configurations. - Understand periodic trends related to valence electrons and atomic radius. - Practice solving fundamental chemistry exam problems through structured written exercises. The course starts with essential terminology and foundational models before building toward orbital notation, electron filling rules, and periodic properties. Designed specifically for beginners and exam candidates, this course requires no prior advanced knowledge. Step into general chemistry and master the basics today.
