Author of "The Flyleaf Periodic Table" Responds Roy W. Clark
Since publication of our letter about the multiple forms of periodic tables presented in the flyleaf of textbooks I have received many replies. To these readers and any others who were puzzled by our recommendation I offer this explanation.

The Periodic Table: Facts or Committees? William B. Jensen
I would like to offer two observations relative to the recent letter of Clark and White on the representation of the f-block elements in the periodic table that relate to some disturbing trends in the attitudes of the chemical community towards the nature and use of the periodic tableattitudes that are implicit, though perhaps not intentionally so, in their letter.

Response to "The Flyleaf Periodic Table" Laurence Lavelle
Clark and White wonder why the chemistry education community has not uniformly adopted just one form of the periodic table. Part of the answer is that the majority who are silent on this issue do not want to be attacked by the vocal proponents who insist that lanthanum and actinium must be in the f-block and lutetium and lawrencium must be in the d-block.

The Flyleaf Table: An Alternative Philip J. Stewart
In their consideration of three ways of treating the f-block elements in the standard periodic table, Clark and White opt to footnote a set 15-elements-wide, including both La and Lu, Ac, and Lr. Their only grounds seem to be that this is what IUPAC chose in 2005, but that decision sounds like an attempt to please everyone, which in the end will please no one.

Sampling the Soils Around a Residence Containing Lead-Based Paints: An X-ray Fluorescence Experiment Steven J. Bachofer
A soil sampling experiment using field portable instruments was conducted at a pre-1950 construction known to have lead-based paint. Students collected data following regulatory protocols at multiple locations within and outside of the house's dripline, reported their results, and provided the owner advice on methods to minimize contact with contaminated soil.

Potassium Metal Is Explosive—Do Not Use It! Andreas Grubelnik, Veronika R. Meyer, Peter Bützer, and Urban W. Schönenberger

News from the Periodic Table: An Introduction to "Periodicity Symbols, Tables, and Models for Higher-Order Valency and Donor–Acceptor Kinships" Henry A. Bent and Frank Weinhold
Proposes that alternative display topologies such as a 2D "left-step" or "step-pyramid" table or 3D "periodic towers" can supplement or supplant the standard periodic table by better emphasizing higher-order patterns of chemical association and reactivity, rather than the physical resemblances of standard-state elemental substances.

Sedimentation Time Measurements of Soil Particles by Light Scattering and Determination of Chromium, Lead, and Iron in Soil Samples via ICP Patricia Metthe Todebush and Franz M. Geiger
In this two-part general chemistry laboratory activity, students study soil samples from home and from campus. In part one, the samples are placed in water and the suspended colloid fraction is separated using filtration, followed by a determination of colloid sedimentation rates via light scattering. In part two, the solid phase of the soil samples is dissolved in acid and analyzed for chromium, lead, and iron using an inductively coupled plasma spectrometer. The experiment can be expanded to include arsenic. Through these experiments students can draw conclusions about the physical and chemical behavior of solid components in soil, paying particular attention to their propensity for transporting and chemically transforming pollutants in the environment.

Copper Metal from Malachite circa 4000 B.C.E. Gordon T. Yee, Jeannine E. Eddleton, and Cris E. Johnson
The experiment starts with a naturally occurring ore, malachite, essentially pure Cu2CO3(OH)2, which is readily available at modest cost in bead form from jewelry stores. Using only a Bunsen burner, a porcelain crucible, and a charcoal briquette, the experiment demonstrates two steps in the ancient processing of copper ore: roasting and reduction. The product is a shiny copper metal bead that can then be hammered, polished, and shown to be electrically conductive.

Application of Light Emitting Diodes to Chemical Analysis: Determination of Copper in Water Juan D. Mozo, Manuel Galán, and Emilio Roldán
In this paper a photometer based on a light emitting diode is described. The light source is a 5-mm LED, which can be replaced in order to select the emission wavelength. A fiber optic is used to conduct light from the LED to the sample, and an inexpensive solid-state light-to-voltage optical sensor is used as a detector. Using a yellow LED (peak emission = 595 nm), copper(II) in the mg/L range can be accurately analyzed.

Ionization Energies, Parallel Spins, and the Stability of Half-Filled Shells Peter Cann
Three methods for explaining the decrease in first ionization energies between group V and group VI elements are described and commented upon. The quantum mechanical origin of the unhelpful concept of half-shell stability is explained in terms of exchange energy, for which the alternative term parallel spin avoidance factor is suggested. It is recommended that for pre-university students the simplest explanation, in terms of Coulombic repulsion between two electrons occupying the same orbital, is adopted: it involves fewer difficult concepts than the other explanations and its predictions are no less accurate.

In Defense of Quantum Numbers Robert M. Richman
A recent paper has argued that the derivation of the periodic table using quantum numbers is a topic that should be eliminated from introductory chemistry courses because it is too abstract, mysterious, and esoteric. A rebuttal is offered based on the claim that it would be wrong to omit discussions of the inductive approach of Mendeleev and the deductive approach initiated by Schroedinger, because they compose the consummate example of that interaction of empirical and rational epistemologies that defines how chemists think.

Designing a Self-Contained Qualitative Analysis Test for Transition Metal Ions Y. S. Serena Tan, B. H. Iain Tan, Hian Kee Lee, Yaw Kai Yan, and T. S. Andy Hor
A challenging self-contained qualitative analysis test for transition metal compounds comprising nine unknowns whereby the unknown solutions can be systematically identified, without relying on external reagents, by inter-mixing the unknown samples. The names of the samples are made known, but their correspondence with the samples is concealed. A representative range of transition metal compounds was selected, together with two complementary main-group compounds. This "9-bottle" test encourages logical deduction and analytical thinking.

The Periodic Building of the Elements: Can a Periodic Table Be Transformed into a Stereo One? Fu-cheng He, Xiang-yuan Li
A periodic table of any size can be transformed into a stereo model which is called the Periodic Building of the Elements (PBE). To construct the PBE a submodel of the main group and the transition elements should be made in advance, and then a submodel of the lanthanides and the actinides is made in a simple procedure. The whole model is obtained by simply combining these two submodels together.

Die Chemischen Elemente: Ein Streifzug durch das Periodensystem by Lucien F. Trueb reviewed by George B. Kauffman
A Ramble through the Periodic System is divided into two parts: Part I, "The Conception of the Elements and the Periodic System" (14 pp), and Part II, "The Elements" (381 pp). The first considers the idea of the elements from Democritus to Lavoisier, the discovery and development of the periodic system, and the origin of the elements, including nucleosynthesis. The second, consisting of 23 chapters, describes each of the elements from hydrogen and its isotopes (16 pp) to the heaviest of the known transactinides (element 112).

Electron Affinities of the Alkaline Earth Metals and the Sign Convention for Electron Affinity John C. Wheeler
It has been known since 1987, both theoretically and experimentally, that the ion Ca- is stable. It is now certain that Sr-, Ba-, and Ra- are also stable, and accurate values for the electron affinities of Ca-, Sr-, and Ba- have been determined. Recommended values for these electron affinities, in the units commonly employed in introductory texts and with the sign convention used here, are 2.37, 5.03, and 13.95 kJ/mol for Ca, Sr, and Ba, respectively.
