The elements in the column on the left each have one electron that they like to donate. From a standard reduction potential table, it is determined that iodine and bromine cannot oxidize water to oxygen because they have smaller reduction potentials than oxygen. Sulfur reacts directly with all the halogens except iodine. Chlorate is a very good oxidizing agent and is very important in matches and fireworks. Halogens therefore react most vigorously with Group 1 and Group 2 metals of all main group elements. Hessler, John. when they react with metals. Thus, iodine and bromine do not react with water.
