WebAll Group 17 (group VIIA or halogen) elements have 7 valence electrons (7 electrons in the valence shell or highest energy level). Atomic radius increases down Group 17 from top to bottom. Electronegativity decreases down group 17 from top to bottom. Chemical reactivity of group 17 elements decreases down group 17 from top to bottom. WebThe fall in reactivity is because the halogens become less good oxidising agents as you go down the group. In the cases of chlorine and bromine, the iron atoms are oxidised to iron …
