Theoretical Alchemy
The alchemists of the Middle Ages attempted a range of unlikely feats, such as transmuting lead into gold, without a solid grasp of the nature of matter. In contrast, modern chemists understand how chemical bonds give substances their structure and properties. In Theoretical Alchemy, Walter Harrison shares insights on chemical bonding and specifically the energy gained in assembling a molecule or solid.
A recurring theme in the book is an approach that Harrison dubs “theoretical alchemy,” which can offer useful insight into how bonds operate. Within this framework, we begin by considering one simple element, e.g., the inert gas argon. We then conceptually remove a proton from the nucleus of one argon atom, turning it into a chlorine nucleus. Next, we place the proton in the nucleus of another argon atom, transforming it into a potassium atom. The electron cloud will shrink a little around the potassium atom and expand around the chlorine atom, and we can understand the behavior of the resulting potassium chloride compound in terms of the simpler inert gas.
Harrison begins with a look at atomic states, including electron density distributions and nuclear structure. He continues with an analysis of hydrides, a discussion that incorporates the behavior of water near metal surfaces, and then turns to aspects of molecules such as electron-electron interactions. Three-dimensional lattices are investigated in a look at simple metals, and a chapter on covalent solids involves the nature of homopolar and compound semiconductors. Further chapters treat ionic compounds, transition and f-shell metals, and transition-metal compounds.
Theoretical Alchemy offers a unique take on a phenomenon that underlies our material world.

Needs an introduction 
September 24, 2011
I struggled through this book, primarily since there was no introductory material at all. I found myself needing to pick up a couple of other books to get to the point where I could understand what was going on. The writing is dense and not very interesting. You need to really want to get to know chemical bonding to tackle this book.
