This book is about how students are taught the periodic table. It reviews aspects of the periodic table’s development, using the history and philosophy of science. The teaching method presented in this book is ideal for teaching the subject in high school and at introductory university level. Chemistry students taught in this new, experimental way are compared with those taught in the traditional way and the author describes how tests found more conceptual responses from the experimental group than the control group. The historical aspects of importance to this teaching method are: the role of the Karlsruhe Congress of 1860; the accommodation of the chemical elements in the periodic table; prediction of elements that were discovered later; corrections of atomic weights; periodicity in the periodic table as a function of the atomic theory; and the accommodation of argon. The experimental group of students participated in various activities, including: discussion of various aspects related to the history and philosophy of science; construction of concept maps and their evaluation by the students; PowerPoint presentations; and interviews with volunteer students.

Learn how medicinal plants work from the chemical level upward Understanding Medicinal Plants: Their Chemistry and Therapeutic Action is designed to teach the chemical concepts necessary to understand the actions of medicinal plants to people who are intimidated by chemistry. This beautifully illustrated, accessibly written guide explores the molecules of medicinal plants and the pharmacology behind their actions on the human body. The book will be valuable to non-science majors, biology majors, interested scientists of different disciplines, and practitioners and students of herbalism and complementary medicine. Understanding Medicinal Plants covers the essentials, including: understanding the symbolism of chemical structure bonding—and predicting useful properties important plant compounds isolation and purification of plant molecules drug delivery and action in the human body the chemistry of antioxidants identification of plant molecules Interest in alternative medicine and herbal products has never been higher than it is now. Understanding Medicinal Plants aims for the middle ground between technical manuals for highly trained individuals and books for the general public that may oversimplify the material. This introductory work provides you with a wealth of suggested reading materials, tables, figures, and illustrations. Three case studies illustrate specific plant drugs and their molecular constituents. This resource also provides an extensive glossary for easy reference. In Understanding Medicinal Plants, you will find a lexicon of medicinally important chemical families found in plants to help you identify and understand the role of constituents such as: alkaloids flavonoids coumarins glycosides amino acids lignans tannins and many more Understanding Medicinal Plants enriches your knowledge of the science behind herbalism and increases your savvy as a consumer of herbal products. This sourcebook will help you better understand the debates about the regulation of medicinal plants and related health care policy debates. With this book, you will be able to interpret media hype about medicinal plants with greater confidence.

The periodic table is one of the most potent icons in science. It lies at the core of chemistry and embodies the most fundamental principles of the field. The one definitive text on the development of the periodic table by van Spronsen (1969), has been out of print for a considerable time. The present book provides a successor to van Spronsen, but goes further in giving an evaluation of the extent to which modern physics has, or has not, explained the periodic system. The book is written in a lively style to appeal to experts and interested lay-persons alike. The Periodic Table begins with an overview of the importance of the periodic table and of the elements and it examines the manner in which the term 'element' has been interpreted by chemists and philosophers. The book then turns to a systematic account of the early developments that led to the classification of the elements including the work of Lavoisier, Boyle and Dalton and Cannizzaro. The precursors to the periodic system, like Döbereiner and Gmelin, are discussed. In chapter 3 the discovery of the periodic system by six independent scientists is examined in detail. Two chapters are devoted to the discoveries of Mendeleev, the leading discoverer, including his predictions of new elements and his accommodation of already existing elements. Chapters 6 and 7 consider the impact of physics including the discoveries of radioactivity and isotopy and successive theories of the electron including Bohr's quantum theoretical approach. Chapter 8 discusses the response to the new physical theories by chemists such as Lewis and Bury who were able to draw on detailed chemical knowledge to correct some of the early electronic configurations published by Bohr and others. Chapter 9 provides a critical analysis of the extent to which modern quantum mechanics is, or is not, able to explain the periodic system from first principles. Finally, chapter 10 considers the way that the elements evolved following the Big Bang and in the interior of stars. The book closes with an examination of further chemical aspects including lesser known trends within the periodic system such as the knight's move relationship and secondary periodicity, as well at attempts to explain such trends.
