Forecasting Periodic Trends: A Semester-Long Team Exercise for Nonscience Majors  John Tierney
Teams of students in a course for nonscience majors identify trends among the properties of elements in the periodic table, use Excel to plot and produce best-fit equations to describe relationships among those properties, and apply the resulting formulas to predict and justify the properties of missing elements.

Probing the Orbital Energy of an Electron in an Atom  James L. Bills
This article answers an appeal for simple theoretical interpretations of atomic properties. A theoretical snapshot of an atom, showing the screened nuclear charge and the electron to be ionized at its radius of zero kinetic energy, enables anyone to approximate its ionization energy.

Are Some Elements More Equal Than Others?  Ronald L. Rich
Presents a new periodic chart with 18 columns but no interruptions of atomic numbers at Lanthanum or Actinum, and no de-emphasis of elements 57-71 or 89-103 by seeming to make footnotes of them. It shows some elements more than once in order to illuminate multiple relationships in chemical behavior.

Predicting the Atomic Weights of the Trans-Lawrencium Elements: A Novel Application of Dobereiner's Triads  Sami A. Ibrahim
Dobereiner's concept of triads remain useful for predicting the properties of the super-heavy elements (113118) and for providing reasonable estimates of the atomic weights of all 16 trans-lawrencium elements.

Valence, Covalence, Hypervalence, Oxidation State, and Coordination Number  Derek W. Smith
It is argued that the terms valence, covalence, hypervalence, oxidation state, and coordination number are often confused and misused in the literature. It is recommended that use of the term valence, and its associated terminology, should be restricted to simple molecular main group substances and to some oxoacids and derivatives, but avoided in both main group and transition element coordination chemistry.

Electronegativity and the Bond Triangle  Terry L. Meek and Leah D. Garner
The dependence of bond type on two parameters, electronegativity difference (??) and average electronegativity (?av), is examined. It is demonstrated that ionic character is governed by the partial charges of the bonded atoms, and metallic character by the HOMOLUMO band gap.

Teaching Molecular Geometry with the VSEPR Model  Ronald J. Gillespie
The difficulties associated with the usual treatment of the VB and MO theories in connection with molecular geometry in beginning courses are discussed. It is recommended that the VB and MO theories should be presented only after the VSEPR model either in the general chemistry course or in a following course, particularly in the case of the MO theory, which is not really necessary for the first-year course.

A Living Periodic Table  James L. Marshall
A complete "living" periodic table of samples of all the elements through uranium is described. In many instances a sample of an element is accompanied by a direct commercial application. This periodic table is very helpful in enabling the student to gain a hands-on understanding of the true nature of the elements--as opposed to the more usual compilation of mere abstract data.

Before There Was Chemistry: The Origin of the Elements as an Introduction to Chemistry  Neil Glickstein
The use of cosmology as an interdisciplinary introduction to a chemistry course is discussed. Students read a variety of nontext sources in order to piece together the events of the early universe that led to the creation of the elements. An introduction to gravity, mass, time, distance, temperature, and density are all possible with thematic cohesion.

Astronomy Matters for Chemistry Teachers  Jay S. Huebner, Robert A. Vergenz, Terry L. Smith
The purpose of this paper is to encourage more chemistry teachers to become familiar with some of the basic ideas described in typical introductory astronomy courses, including those about the origin of elements and forms of matter. These ideas would enrich chemistry courses and help resolve some basic misconceptions that are expressed in many introductory texts and journal articles for chemistry teachers.
