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.

Measurement of the Isotopic Ratio of 10B/11B in NaBH4 by 1H NMR Murray Zanger and Guillermo Moyna
A simple and remarkably accurate method for estimating the isotopic ratio between 10B and 11B through the use of 1H nuclear magnetic resonance (NMR) spectroscopy is presented. The experiment relies on the splitting caused by 10B (I = 3) and 11B (I = 3/2) on the 1H signal of a proton directly bound to boron, a phenomenon readily observed on an aqueous sample of NaBH4. In combination with a brief lecture or prelaboratory presentation, this laboratory can serve to introduce students to magnetic properties as well as theoretical and experimental aspects of NMR spectroscopy as early as the freshman-level chemistry.

A Strategy for Incorporating Hands-On GC-MS into the General Chemistry Lecture and Laboratory Courses Perry C. Reeves and Kim L. Pamplin
Students use the GC-MS to obtain spectra of the various halobenzenes. This vividly illustrates the differences in isotopic distributions of the halogens and the complications these differences present in calculating molar masses of compounds. The isotopic distribution of iron is then obtained from the mass spectrum of Fe(CO)5, and the students calculate the atomic mass of iron from this data.

No, the Molecular Mass of Bromobenzene Is Not 157 amu: An Exercise in Mass Spectrometry and Isotopes for Early General Chemistry Steven M. Schildcrout
Even with no background in bonding and structure, students can successfully interpret the output of a modern research instrument. They learn to identify an isotope pattern, assign chemical formulas to ions giving mass spectral peaks, calculate an average atomic weight (for bromine) from measured isotopic abundances, and write balanced equations for ion fragmentation reactions.

A Different Approach to a 3-D Periodic System Including Stable Isotopes Alexandru T. Balaban
On a Periodic System with the two dimensions represented by Periods and Columns, one may stack each stable nuclide of an element along the third dimension. This "Downtown Area" representation is helpful for interconnecting concepts of: element, isotope or nuclide (stable vs. radioactive), atomic weight, atomic number, mass number.

From the Research Laboratory to the Classroom: A Partners-in-Science Experience Robert Zafran
This article describes the usage of two diametrically different, spherically shaped polymer balls known to science educators as Happy/Unhappy Balls. The unique property of the polynorbornene (Norsorex), "Unhappy" ball, its reluctance to bounce, is paired with the normally bouncing polychloroprene (neoprene) "Happy" ball to teach students observational skills necessary for the effective application of scientific reasoning processes needed for investigative analysis.
