Foundations of Chemistry: Atomic Structure

Have you ever wondered what makes up the matter all around us? Understanding the structure of the atom is the key to unlocking the secrets of chemistry and the physical world. This text-based course guides you through the foundational principles of atomic theory, from early historical models to our modern understanding of subatomic particles. By reading our structured explanations and working through targeted practice questions, you will build a rock-solid foundation in chemistry. What you'll learn: Understand the historical development of atomic models, including Thomson, Rutherford, and Bohr; Identify the properties and locations of protons, neutrons, and electrons within the atom; Calculate atomic mass, atomic number, and write electron configurations for various elements; Explore isotopes and isobars, and understand their practical applications in modern science; Practice solving conceptual chemistry questions and multiple-choice exercises to reinforce your learning. The course begins with essential terminology and the earliest scientific discoveries, gradually advancing to electronic configurations and the rules governing how atoms interact. You will solidify your knowledge through written review questions and detailed answer explanations. This course is designed for beginning chemistry students, school learners, or anyone looking to refresh their understanding of fundamental science with no prior prerequisites.
