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.

Illustrating the Concepts of Isotopes and Mass Spectrometry in Introductory Courses: A MALDI-TOF Mass Spectrometry Laboratory Experiment  Nancy Carter Dopke and Timothy Neal Lovett
This article describes a matrix-assisted laser desorption/ionization (MALDI) mass spectrometry experiment in which students prepare peptide samples for mass analysis and then collect and analyze mass spectral data. The lab provides hands-on experience with research instrumentation and reinforces the concepts of isotopes, molecular masses, and molecular formulas.
