Abstract. Chlorine, bromine, and iodine are used to illustrate how intermolecular forces of attraction play a key role in determining the physical state of these elements. An existing laboratory exercise has been modified to a student inquiry-based classroom exercise suitable for a high school AP chemistry class or a college freshman-level introductory chemistry course.
