Foundational Chemistry: Atoms, Molecules, and Molar Mass

Chemistry starts with understanding the smallest units of matter. If you are struggling with the concepts of atoms, elements, and compounds, this course provides the clear, written instruction you need to build confidence in the subject. By the end of this course, you will have a rock-solid conceptual foundation in atomic theory and the mathematical laws that govern how atoms combine. This knowledge is crucial for success in subsequent chemistry studies and understanding the world around you. What you'll learn: * Understand the historical development of atomic theory, from Dalton to modern models of subatomic particles. * Master the Laws of Chemical Combination, including the Law of Conservation of Mass and the Law of Definite Proportions. * Practice using the mole concept to calculate molar mass, empirical formulas, and the number of particles in a substance. * Learn the basic rules for chemical nomenclature and how to write formulas for simple ionic and covalent compounds. * Apply foundational stoichiometric principles to balance simple chemical equations. * Analyze the structure of atoms, including isotopes and isobars, and their relationship to the periodic table. The course begins with fundamental definitions and historical context, moves into the structure of the atom and the laws of combination, and concludes with practical applications of the mole concept and basic equation writing. This course is designed for absolute beginners in chemistry or those needing a thorough review of fundamental concepts. No prior scientific knowledge is required. Begin your journey into the world of chemistry and unlock the secrets of matter.
