When an element in group 7 takes part in a reaction, its atoms outer shells gain an electron and form negatively charged ions, called anions. Fluorine is the most reactive element of all in Group 7. Chlorine is more reactive than the iodine in potassium iodide solution: Word equation: They react with metals to form metal halides. The order of reactivity is: chlorine > bromine > iodine. The reaction is slow. Different combinations of halogen solution and salt solution are tested. Bromine will displace all halides except fluoride and chloride, and so on. a less reactive halogen from solutions. . Metal +  Halogen ———–> metal salt (halide), Example: Sodium + Chlorine ———-> Sodium chloride, The salts that halogens form when they react with metals are called halides (chloride, bromide, iodide for example).
