Master all four quantum numbers (principal, angular momentum, magnetic, and spin) and use them to predict electron behavior with confidence
Write and interpret electron configurations for elements across the periodic table
Calculate effective nuclear charge (Zeff) using Z − S and explain how it drives periodic trends
Predict and compare trends in electronegativity, ionization energy, and atomic radius across periods and groups
Apply VSEPR theory to determine both the electronic geometry and molecular shape of a given compound
Distinguish between electronic geometry and molecular shape, especially when lone pairs are present
Identify regions of electron density around a central atom and predict resulting shapes — tetrahedral, trigonal planar, bent, and more
Use the scientific method as a framework for structuring chemical reasoning and experimental thinking

Enid Osborn is a forward‑thinking environmental science educator and research scientist with dual master’s degrees in Environmental Engineering and Chemistry from Michigan Technological University and UC San Diego, respectively. With hands‑on experience in cutting‑edge analytical techniques and laboratory management, Enid excels at translating complex scientific data into engaging, interactive lessons. Her work in research and product development underscores her commitment to fostering scientific curiosity and sustainable practices in the classroom.
High School Chemistry Fundamentals is the year-round supplemental class for driven students who want more than a passing grade — they want to actually own the material. While school-year schedules force teachers to move on and students to make tradeoffs, this class gives you dedicated space to build the deep, durable mastery of chemistry's most foundational concepts. From quantum numbers and electron configurations to periodic trends and VSEPR theory, you'll work through the skills that show up again and again — on future tests, in future courses, and on standardized exams. This isn't about keeping up; it's about getting ahead by making sure your foundation is genuinely solid while other students are still patching cracks.
