WebThe order of reactivity is therefore: chlorine > bromine > iodine. A more advanced treatment identifies the halogens as oxidising agents, accepting an electron to form halide ions: Cl 2 (aq) + 2I - (aq) → I 2 (aq) + 2Cl - (aq)

WebIt also looks at the bond strengths of halogen-halogen bonds and of hydrogen-halogen bonds. Halogens as oxidising agents . . . Describes and explains the trend in oxidising ability of the Group 7 elements based on the reactions between one halogen and the ions of another one - for example, between Cl 2 and I-ions from salts like KI. fish city grill pearland txWebAs you go down group 7, reactivity of the halogens decreases because: The atomic mass of the halogens increases. They increase in electron shells; so the atoms are larger as you go down the group. Therefore, the attraction of the outer electron to the nucleus decreases as you go down group 7.
