About this course

Ever wondered what makes up the world around us at the most fundamental level? Understanding the structure of the atom is the key to unlocking chemistry, physics, and the material sciences. This text-based course guides you from the absolute basics of atomic theory to a clear, modern understanding of how atoms are structured and how they interact. You will transition from memorizing terms to truly understanding the behavior of matter. What you'll learn: - Understand the core properties of protons, neutrons, and electrons. - Trace the evolution of atomic models from early theories to modern electron cloud concepts. - Calculate atomic numbers, mass numbers, and distinguish between isotopes and isobars. - Master electron configuration and the rules for distributing electrons in shells. - Determine valency and predict how elements will behave in chemical reactions. - Practice solving foundational chemistry problems with step-by-step written walkthroughs. We begin with essential terminology and the historical discoveries that shaped our understanding of the atom. From there, you will explore subatomic details, electron arrangements, and the basics of chemical bonding through clear explanations and practical written exercises. This course is designed for beginners, students preparing for introductory science exams, and anyone curious about the building blocks of the universe. No prior chemistry background is required. Start reading now to build your foundational knowledge of atomic science!
