Foundations of Chemistry: Atomic Structure and Measurement

Chemistry relies on precise measurement and a deep understanding of the atom's fundamental nature. This course provides the critical theoretical knowledge and quantitative skills necessary to build a strong foundation in the chemical sciences. By the end of this course, you will move beyond simple definitions to grasp how scientists measure matter, analyze uncertainty, and model the behavior of subatomic particles. You will gain confidence in applying the rules of scientific notation and significant figures to ensure data integrity in all your chemical calculations. What you'll learn: * Learn the fundamental laws governing the structure of matter and the historical development of atomic theory. * Master the rules for using scientific notation, dimensional analysis, and identifying significant figures in calculations. * Understand the properties of subatomic particles, isotopes, and how atomic mass is determined using modern methods. * Apply the quantum model to describe electron configurations, energy levels, and orbital shapes. * Practice calculating and interpreting common forms of electromagnetic radiation related to atomic transitions. The course begins with defining matter and energy, establishing the rules of scientific measurement and error analysis. It then progresses systematically through the historical models of the atom, culminating in the modern quantum mechanical description of atomic structure and electron behavior. This course is designed for absolute beginners in chemistry, high school students, or anyone seeking a rigorous introduction to chemical principles. No prior scientific knowledge or advanced mathematics is required to begin. Start building your expertise in the language and science of chemistry today.
