Introductory Chemistry: Periodic Classification and Valency

Chemistry does not have to be a confusing maze of memorization and intimidating chemical reactions. Understanding the periodic table is the absolute key to unlocking how elements behave, bond, and react with one another. This text-only course guides you from the absolute basics of atomic structure to a clear understanding of periodic trends and chemical bonding. You will build a solid foundation in chemistry, transforming how you view elements and their interactions. What you will learn: Learn the fundamental history and evolution of periodic classification, from early attempts to the modern periodic table; Understand atomic structure, valency, and how electrons determine an element's chemical properties; Master key periodic trends, including atomic size, electronegativity, and metallic character; Predict chemical reactions and bonding behaviors based on an element's position in the periodic table; Practice solving chemistry problems with step-by-step written exercises and clear explanations. You will start with core terminology and foundational definitions before moving on to modern electronic configurations and practical applications of periodic trends. Perfect for absolute beginners, students preparing for introductory exams, or anyone looking to build a strong foundational understanding of chemistry with no prior knowledge required.
