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.

Revisiting the Electric Pickle Demonstration Michelle M. Rizzo, Tracy A. Halmi, Alan J. Jircitano, Martin G. Kociolek, and Jerry A. Magraw The electric pickle demonstration has long been used to explore the atomic emission of sodium ions, which emit a brilliant yelloworange glow. The emission from other metal ions including lithium, potassium, strontium, and barium can also be demonstrated by pickling cucumbers with the corresponding chloride salt.

Teaching Chemistry with Electron Density Models Gwendolyn P. Shusterman and Alan J. Shusterman This article describes a powerful new method for teaching students about electronic structure and its relevance to chemical phenomena. This method, developed and used for several years in general chemistry and organic chemistry courses, relies on computer-generated three-dimensional models of electron density distributions.

Line spectrum demonstration for the large lecture hall Driscoll, Jerry A. The undergraduate's learning experience with quantum mechanics and Bohr's theory can be greatly enhanced by the presentation of a line spectrum demonstration, but these are often hard to see in large lecture halls. The authors present a physical arrangement of an apparatus that can be easily assembled to allow for easier student viewing in a lecture-hall situation. Driscoll, Jerry A. J. Chem.

Energy level diagrams and extranuclear building of the elements Keller, R. N. Simplified diagrams showing the approximate order of electronic energy levels in atoms and mnemonic devices to aid in predicting electronic configurations for atoms are often misleading with respect to the actual energy of binding of the electrons in atoms and ions of the transition elements.

A new periodic table based on the energy sequence of atomic orbitals Walker, W. R.; Curthoys, G. C. Since the theory of atomic and molecular orbitals has proven to be of such value in interpreting the data of inorganic chemistry, it is hoped that a new periodic table based on the energy sequence of atomic orbitals will be an aid to the further systematizing of chemical knowledge.
