Reactivity down group 17
WebReactivity will decrease as you travel down group 7 in the periodic table. Group 7 elements need to gain an electron to become stable as they need 8 electrons in their outer shell. … WebJan 8, 2024 · The chemical reactivity of group 17 elements decreases down the group. So down the group there is an increase in the atomic radius and hence the effective nuclear force decrease as the atomic radius increases and this leads to the decreased chemical reactivity down the group.

The high reactivity of halogens is due to the following reasons : (i) Low dissociation enthalpies All the halogens have very low dissociation enthalpies. As a result, they can readily dissociate into atoms and react with other substances. (ii) High electron gain enthalpy
