3 мая 2016 г. · As the atomic number increase, the reactivity decreases. That is because each one of them 'wants' to complete their outer electron shell by adding one electron. Why does reactivity decrease down in Group 17 of the periodic ... What happens to the reactivity of halogens as we go down the ... Why do the reactions of halogens with hydrogen become less ...

As, down the group, the amount of electron shielding increases, and the electron becomes less attached to the nucleus.

The reactivities of the halogens(17th group) decrease down the group ( At < I < Br < Cl < F). This is due to the fact that atomic radius increases in size.
