Chem120 week 1 concepts - Study guides, Class notes & Summaries

ATOMIC STRUCTURE In many ways, this lesson is the start of your journey into chemistry. In this foundational lesson, we will learn about the building blocks of matter: atoms. Alchemists, the precursors to chemists, had a saying: “As above, so below”. A modern interpretation of this saying is that the properties of what we can see can help us understand the properties of what we cannot. In this lesson, we will learn how the properties of atoms determine the properties of the world around us.
