Fluoride is used in toothpaste to strengthen enamel so as to prevent cavities. Chlorine is used in bleach, and iodide is put into salt to prevent goiter. All of these elements have similar behavior because their outermost valence shells have 7 electrons, which places them in the same group on the Periodic Table (group 17).
