Foundational Atomic Structure and Chemical Bonding

Have you ever wondered what makes up the world around you and how matter behaves? This course provides a clear, conceptual introduction to the fundamental building blocks of chemistry: atoms and molecules. By the end of this course, you will have a solid foundation in modern atomic theory, including electron arrangement, quantum numbers, and the forces that drive chemical interactions. You will be able to interpret the periodic table based on electron configuration and predict the basic type of bond formed between different elements. What you'll learn: * Understand the historical development of atomic models, from Dalton to the modern quantum mechanical view. * Identify and describe the properties of subatomic particles (protons, neutrons, electrons) and isotopes. * Master the rules for electron configuration, including the use of quantum numbers and orbital notation (s, p, d). * Analyze how atomic structure determines chemical properties and periodic trends like ionization energy and electronegativity. * Apply the principles of ionic and covalent bonding to predict the formation and basic structure of simple molecules. * Practice calculating basic metrics like atomic mass, molar mass, and mole concepts necessary for quantitative chemistry. The course begins with essential terminology and the history of atomic theory, progressing systematically through electron arrangement and concluding with an explanation of fundamental chemical bonding types. Practical examples and written exercises are integrated throughout to reinforce conceptual understanding. This course is designed for absolute beginners with no prior chemistry knowledge, or anyone looking for a comprehensive refresher on foundational concepts. No scientific prerequisites are required—just a willingness to read and practice. Start building your core chemistry knowledge today.
