This arrangement reflects the author's belief that beginning students can understand statistical mechanics better than chemical thermodynamics.Īimed at first-year college students who plan to major in chemistry or closely related fields, the book is written in a logical, clear, and understandable style. Statistical mechanics is introduced before thermodynamics, and the discussion of thermodynamics is based on it. No attempt is made to solve the Schrodinger wave equation for other systems, but the wave functions of hydrogen-like electrons are presented and discussed in some detail, and the quantum states for other systems are also covered.

The quantized energy levels of a particle in a box are derived by means of a simple assumption about the relation of the de Broglie waves to the walls of the box. The principles of quantum mechanics are discussed on the basis of the de Broglie wavelength of the electron. In this extensively revised and updated third edition, the Nobel Prize winning author maintains an excellent balance between theoretical and descriptive material, although the amount of descriptive chemistry has been decreased somewhat, and the presentation of the subject, especially in relation to the nonmetals, has been revised in such a way as to permit greater correlation with the electronic structure of atoms, especially electronegativity. Pauling attempted to correlate the theories with descriptive chemistry, the observed properties of substances, to introduce the student to the multitude of chemical substances and their properties. Those principles included modern theories of atomic and molecular structure, quantum mechanics, statistical mechanics, and thermodynamics.

When it was first published, this first-year chemistry text revolutionized the teaching of chemistry by presenting it in terms of unifying principles instead of as a body of unrelated facts. 'An excellent text, highly recommended.' Choice
