Unit 3 - Atomic Structure

In this unit, we will learn about the development and evidence for the theory of modern atomic structure.  Beginning with Dalton's "Solid Sphere" model, we will explore the discoveries which have progressively led to the complex and beautiful Quantum-Mechanical model which underpins much of our understanding of how the atom behaves.
