Chemistry : international student version
The seventh edition of our textbook continues to emphasize the molecular nature of matter, strong problem solving, and clarity of writing that was the basis of the sixth edition of Chemistry by James E. Brady, Neil D. Jespersen, and Alison Hyslop. The relationship between the molecular level and the observable macroscopic properties of matter is presented in increased detail to reinforce and expand this fundamental concept.
Philosophy and Goals
The philosophy of the text is based on our conviction that a general chemistry course serves a variety of goals in the educa¬tion of a student. First, of course, it must provide a founda¬tion in the basic facts and concepts of chemistry upon which theoretical models can be constructed. The general chemistry course should also give the student an appreciation of the central role that chemistry plays among the sciences, as well as the importance of chemistry in society and day-to-day liv¬ing. In addition, it should enable the student to develop skills in analytical thinking and problem solving. With these thoughts in mind, our aim in structuring the text was to provide a logical progression of topics arranged to provide the maximum flexibility for the teacher in organizing his or her course. In this text, we were guided by three principal goals. The first was to strengthen the connection between observa¬tions on the macroscopic scale and the behavior of atoms, molecules, and ions at the atomic level while introducing all concepts in a logical and understandable manner. The second was to further enhance and streamline our approach to teaching effective problem-solving skills. This includes emphasis on estimation and answer checking. The third goal was to provide a seamless, total solution to the General Chemistry course by fully integrating the textbook content with online assessment, answer-specific responses, and resources delivered within WileyPLUS.
Emphasizing the Molecular View of Nature
The value of the molecular approach in teaching chemistry is well accepted and has always been a cornerstone in the approach taken by Jim Brady and his co-authors in present¬ing chemistry for many years. From his first text, in which novel three-dimensional computer-drawn representations of molecules and crystal structures were presented and observed using stereoscopic viewers, up through the 6th edition of this text, the atomic/molecular view has dominated the pedagogy. This new edition builds on that tradition by employing the "molecular basis of chemistry" as a powerful central theme of the text. Through this approach, the student will gain a sound appreciation of the nature of matter and how structure deter¬mines properties. Some actions we have taken to accomplish this are as follows:
Chapter Zero: A Very Brief History of Chemistry This new edition of the textbook begins with the formation of atoms from the origin of the universe. By discussing how atoms were initially formed and then moving on to the structure of the atoms through discoveries of the subatomic particles, we lay the groundwork for the atomic and molecular view of matter and outline how these concepts are used throughout the text. We provide a brief introduction to the distribution of elements throughout the earth and introduce students to the way we visualize molecules and chemical reactions.
Macro-to-Micro Illustrations To help students make the connection between the macroscopic world we see and events tiiat take place at the molecular level, we have a substantial number of illustrations that combine both views. A photograph, for example, will show a chemical reaction as well as an artists rendition of the chemical interpretation of what is taking place between the atoms, molecules, or ions involved. The goal is to show how models of nature enable chemists to better understand their observations and to get students to visualize and describe events at the molecular level.
