Reactivities of the Group 7 Elements (The Halogens)
During this lab activity, chemists discover the reactivities of chlorine, bromine, and iodine as examples of the halogens. They use a displacement reaction as a test by adding other compounds and observing for a color change. The lab sheet is compact, well-written, and includes a data table and conclusion questions. It is a valuable investigation when introducing properties of elements to your chemistry charges.
