Examines the reasoning behind views of atoms and molecules held by students (n=48) and investigates how mental models may assist or hamper further instruction in chemistry. Reports that students prefer models of atoms and molecules that depict them as discrete, concrete structures. Recommends that teachers develop student modeling skills and…

Reviews the areas of laser chemistry, photochemistry, infrared lasers, and laser induced molecular reactions. (SL)

Describes a practical and visual way of extending the concept of symmetry present in nature to the quantum structure of molecules. (SL)

Describes a 12 hour minicourse in Huckel molecular orbital (HMO) theory presented as part of a senior level chemical bonding course. (SL)

Argues for including several key ideas in every introductory general chemistry course, including the phenomena of chemistry, the organization and classification of matter, atomic structure, molecular bonding and molecular structure, the language of chemistry, the mole, chemical reactions and reactivity, chemical kinetics, chemical equilibrium, and…

Introduces a simple one-dimensional model of a diatomic molecule that can explain all the essential features of a real two particle quantum mechanical system and gives quantitative results in fair agreement with those of a hydrogen molecule. (GA)

Discusses the energy levels of 3d and 4s electrons. (SL)

Formulae are proposed for the distinct cases of monatomic and diatomic gas volumes. Eight figures illustrate the article. (Author/MA)

Discusses Bohr's atomic theory from a chemical, rather than a physical, standpoint. (MLH)

A brief introduction to the periodic table of the elements is presented. The periodic relationships are demonstrated through the use of seven tables which include a breakdown of the periodic table by groups or families, valence ring electron populations by period, electronic configurations of the elements, electron configurations of the elements…

Describes the static and dynamic structural features for metal derivatives of cyclopentadiene. (SL)

Reviews the subject of the electronic structures of metals which produce magnetism. (SL)

Discusses the role of semiclassical theory in chemical physics both as a computational method and conceptual framework for interpreting quantum mechanical experiments and calculations. Topics covered include energy wells and eigenvalues, scattering, statistical mechanics and electronically nonadiabiatic processes. (JM)

It is shown that exact pseudopotentials for excited states of hydrogen atoms can be derived. A very simple, novel application of pseudopotential method which displays vividly some of its limitations is presented. (Author/GA)

Explains using the linear combination of bonding orbitals methods; why two different diagrams are used to represent the molecules when the properties of homonuclear diatomic molecules are being discussed. (GA)
