As 2019 has been declared the International Year of the Periodic Table, it is appropriate that Structure and Bonding marks this anniversary with two special volumes. In 1869 Dmitri Ivanovitch Mendeleev first proposed his periodic table of the elements. He is given the major credit for proposing the conceptual framework used by chemists to systematically inter-relate the chemical properties of the elements. However, the concept of periodicity evolved in distinct stages and was the culmination of work by other chemists over several decades. For example, Newland’s Law of Octaves marked an important step in the evolution of the periodic system since it represented the first clear statement that the properties of the elements repeated after intervals of 8. Mendeleev’s predictions demonstrated in an impressive manner how the periodic table could be used to predict the occurrence and properties of new elements. Not all of his many predictions proved to be valid, but the discovery of scandium, gallium and germanium represented sufficient vindication of its utility and they cemented its enduring influence. Mendeleev’s periodic table was based on the atomic weights of the elements and it was another 50 years before Moseley established that it was the atomic number of the elements, that was the fundamental parameter and this led to the prediction of further elements. Some have suggested that the periodic table is one of the most fruitful ideas in modern science and that it is comparable to Darwin’s theory of evolution by natural selection, proposed at approximately the same time. There is no doubt that the periodic table occupies a central position in chemistry. In its modern form it is reproduced in most undergraduate inorganic textbooks and is present in almost every chemistry lecture room and classroom. This first volume provides chemists with an account of the historical development of the Periodic Table and an overview of how the Periodic Table has evolved over the last 150 years. It also illustrates how it has guided the research programmes of some distinguished chemists.

The Periodic Table: Its Story and Its Significance traces the evolution and development of the periodic table, from Mendeleev's 1869 first published table and onto the modern understanding provided by modern physics.

Interviews conducted with Eric Scerri at the Chemical Heritage Foundation on the Periodic Table Part 1Interviews conducted with Eric Scerri at the Chemical Heritage Foundation on the Periodic Table Part 2 This book contains key articles by Eric Scerri, the leading authority on the history and philosophy of the periodic table of the elements and the author of a best-selling book on the subject. The articles explore a range of topics such as the historical evolution of the periodic system as well as its philosophical status and its relationship to modern quantum physics. This volume contains some in-depth research papers from journals in history and philosophy of science, as well as quantum chemistry. Other articles are from more accessible magazines like American Scientist. The author has also provided an extensive new introduction in order to integrate this work covering a period of two decades. This must-have publication is completely unique as there is nothing of this form currently available on the market.

Aligned to Common Core State Standards, Elements and the Periodic Table present the basics of the Periodic Table in an easy-to-understand, easy-to-master way! It contains fun activities, transparency masters, quizzes, tests, rubrics, grading sheets, and more. From basic elements to table organization, Elements and the Periodic Table is the essential handbook for middle-school science!

Decoding the Periodic Table In the year 1809 Russian Chemist Dimitri Ivanovich Mendeleev published the first Chemical Periodic Table of the Elements. Since then scientists developed a theory that every element consists of a tightly packed mass of protons and neutrons which is surrounded by concentric spheres which are occupied by orbiting electrons. This concept is known as the Standard Model, but it is flawed, because it cannot accommodate gravity. For many decades researchers, including this author in the late 1960's, tried to formulate theories that in a comprehensive way would unite all physical designs and phenomena under a common denominator, but to no avail. The String Theory is one of them but it has found no success. In 1989 the author of the book made a fresh start again with the notion that particles such as the proton, neutron and electron would not be round, but that they would have straight-lined, square or cubic configurations, because the Periodic Table's had quadratic numbers in their quantities of elements, such as: Period 1 ? with 2 elements: 2 = 2x12, Periods 2 & 3 ? 8 = 2 x 22, Periods 4 & 5 ? 18 = 2 x 32 and Period 6 & 7 ? 32 2 x 42. This might indicate square structural relationships, lets give it a try! It worked, it took 20 years to do it, it was a fascinating journey, falling down and getting up again and again, working without a computer, with all figures hand-drawn, and discovering that the forces that make the nuclear mass of the neutron do that by multiplying two force-filled cubic volumes, as in [3F]6 = [3F x 3F x 3] X [3F x 3F x 3F] = 1838.2656.

Here, Eric Scerri looks at the trends in properties of elements that led to the construction of the periodic table, and how the deeper meaning of its structure gradually became apparent with the development of atomic theory and quantum mechanics, so that, as Scerri puts it, one science, physics, arguably came to colonize another, chemistry, although such a view is resisted by chemists. Scerri shows that quantum mechanics is absolutely central to chemistry, as it underlies the behaviour of all of the elements and their compounds, and therefore underpins the structure of the periodic table. Concluding with an overview of the huge variety of periodic tables that have been proposed in the print media and on the Internet, he explores the debated question of whether there is an optimal periodic table and what form it might take. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly.

These and more science concepts are presented in a way that makes them more accessible to students and easier to understand. Written to grade and using simplified language and vocabulary and comprised of reading passages, student activities, crossword, word search, comprehension quiz and color mini posters, our resource can be used effectively for test prep and your whole-class. All of our content is aligned to your State Standards and are written to Bloom's Taxonomy and STEM initiatives.

Aligned to Literacy in Science and Technical Subjects, this volume helps students understand the central ideas of Mendeleyev's periodic law. Mendeleyev's major breakthrough was his arranging of the elements in sequence by atomic weight but recognizing that there were gaps where no elements had yet been discovered. This account of Medeleyev's struggling childhood in Tobolsk, Siberia, teaching in St. Petersburg, writing The Principles of Chemistry, and development of the table and how his idea was challenged by the scientific community will captivate readers and show them what it means to pursue a question significant enough to follow for a lifetime.
