Atomic and Nuclear Chemistry, Volume 1: Atomic Theory and Structure of the Atom presents the developments in classical atomic chemistry in the 19th century. This book discusses the atomic theory in terms of existing ideas on nuclear structure and the wave mechanics of electrons in atoms.

Organized into six chapters, this volume begins with an overview of the origin of the atomic theory. This text then explores Berzelius's atomic weight tables. Other chapters consider Dalton's conception of an atom as a hard dense sphere. This book discusses as well the significant results of the simple wave mechanical treatment. The final chapter deals with the determination of the Avogadro's number, which enabled the actual masses of atoms and molecules to be determined.

This book is a valuable resource for atomic physicists, chemists, and research workers. First-year university students who are taking chemistry as a subsidiary subject will also find this book useful.
