WebWhy does reactivity increase down group 1? Click the card to flip 👆 The number of electron shells increases down the group so there is more electron shielding. As a result, there is weaker attraction between the positive nucleus and outer shell electron. This means it is easier to remove an outer shell electron to form a positive metal ion. WebAug 21, 2024 · On moving down group 1, the ionization enthalpies decrease. This means that the energy required to lose the valence electron decreases.
