The two versions of An
Introduction to Chemistry present the same information, but they
do it in a different order.
Many instructors like getting to
chemical reactions early, and students like postponing the
math-related topics of chemistry. To make this possible, the
chemistry-first version postpones the math topics until mid-book
(Chapters 8, 9, 10, and 13 mostly), presents a brief
introduction of atomic theory and bonding early (Chapters 2 and
3) that is completed later (Chapters 11 and 12), and gets to
chemical changes earlier than other texts (Chapters 4-6).
(Chapter 8 on unit conversions was written so it could be
presented early...after Chapter 1.) You can get more information
on this version from its preface and table of contents.

Many instructors and students
prefer to move from simple to more complex...atoms to elements
to bonding to compounds to chemical changes...in a more
systematic way. The atoms-first version provides a more complete
description of atomic theory and bonding early (Chapters 3-5)
and describes chemical reactions later (Chapters 7-9). It also
presents the math-related topics earlier. It has two fewer
chapters because the chemistry-first version's chapter on energy
was separated into parts and put into two other chapters, and a
similar thing was done with the chemistry-first chapter on mole
calculations dealing with chemical formulas. You can read more
