Product Information

Chemistry teacher Frank Stevens developed an easy-to-use device for teaching students how to write simple chemical formulas. The Ion Formula Finder features two dials; one listing the charges on positive ions and the other the charges on negative ions. As students turn the dials the ions appear in the windows. By flipping the Finder over, they can read how the formula should be written. The Finder can be used for any compound with 1–4 positive charges and 1–3 negative charges. Includes 30 Ion Formula Finders and an instruction sheet. Grades 9–12.
