III: The Geometry of Orbitals

This volume continues the *How Atoms Form Molecules* series by focusing on the geometry of orbitals.

Rather than treating orbital drawings as separate shapes to memorize, the book develops a geometric model for seeing how the orbital families relate to one another. It begins with the basic quantum-mechanical language of orbitals, then translates that language into visual scaffolds based on symmetry, nodal planes, polyhedra, and nested spherical boundaries.

The chapters move from s- and p-orbitals into the more complex d- and f-orbital families. The appendix provides additional support for readers who want the deeper structure behind the model, including summary tables, glossary terms, construction steps, nested orbital families, and notes on how geometry constrains the shapes.
