Halogens are the 17th group on the Periodic Table and the elements included are the following: Fluorine, Chlorine, Bromine, and Iodine. Did you know that you use Fluorine when you brush your teeth? Fluorine is so reactive that it attacks glass and quartz, as well as causing most metals to burst into flames. Chlorine is a highly toxic gas with a pale yellow-green color. Chlorine is used in your bleach and it's used as a disinfectant agent. Chlorine destroys the bacteria on your clothing and in your infections. Bromine is a reddish-orange liquid with a choking odor. We use Bromine when we are putting out Fires because they are in the Fire extinguisher, sedatives, antiknock agents for gasoline, and insecticides. Bromine is in the sedatives used to put patients to sleep during a surgery. Iodine is an intensely colored solid with an almost metallic luster. It is sublimed when heated and turns into a violet colored gas. It is also used as a disinfectant.
