Paramagnetism: Compounds Vials of a number of compounds (NaCl, MnSO4, FeSO4, CoCl2, NiSO4, ZnSO4, K4Fe(CN)6, [Co(NH3)6]Cl3, [Ni(NH3)6]Cl2, and H2O) are hung from a thread. When a magnet is brought near, some of the vials are attracted.

Paramagnetism: Oxidation States of Manganese Manganese(III) oxide, with 4 unpaired electrons per Mn atom, is more strongly attracted to a magnet than is manganese(IV) oxide, with only 3 unpaired electrons per Mn atom. Potassium permanganate, a compound of Mn(VII), has no unpaired electrons and is not attracted to a magnet.

Teaching Avogadro's Hypothesis and Helping Students to See the World DifferentlyBrett Criswell This article uses a model from educational psychologyChi's theory of ontological misclassificationto explain the source of students' difficulties in understanding Avogadro's hypothesis and provide a method to successfully teach this fundamental concept. Criswell, Brett. J. Chem. Educ.2008, 85, 1372.

Forecasting Periodic Trends: A Semester-Long Team Exercise for Nonscience MajorsJohn 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. Tierney, John. J. Chem. Educ.2008, 85, 1215.
Interactive Electron ConfigurationsWilliam F. Coleman An application that allows students to drag electrons onto energy levels to construct electron configurations for atoms up to atomic number Ar. The student is responsible for obeying the fundamental rules of quantum mechanics.
