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.

Trends in Ionization Energy of Transition-Metal Elements  Paul S. Matsumoto
Examines why, as the number of protons increase along a row in the periodic table, the first ionization energies of the transition-metal elements are relatively steady, but that for the main-group elements increases.

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.

The periodicity of electron affinity  Myers, R. Thomas
In general, the values of electron affinity for the elements can be understood in terms of their ground state electron configuration, and the screening (effective nuclear charge) exerted on the added electron by the electrons already present in the neutral atom.

Principles of electronegativity Part I. General nature  Sanderson, R. T.
The concept of electronegativity has been modified, expanded, and debated. The concept can be used to help students gain valuable insights and understanding of the cause-and-effect relationship between atomic structure and compound properties. This is the first in a series of articles that explores the important concept of electronegativity.

Exchange stabilization and the variation of ionization energy in the pn and dn series  Blake, Antony B.
This article is concerned with two types of ionizations that are of special importance to chemists. The author's main purpose is to clarify current textbook interpretations of the peculiar decrease in ionization energy following completion of a half-filled p or d shell.
