The reactivity of group 17 elements differ as you move down the periods. Group 17 elements are missing 1 electron from their valance shell making them highly votile and reactive.I'll try not to make this confusing:1. As elements get bigger, they have a higher level of reactivity. (More "pull" needed from protons in the nucleus in order to keep valance shell electrons in orbit).2. As you move from left to right in the groups, you have a higher level of reactivity.3. Groups 1 and 17 have the highest levels of reactivity (except hydrogen in group 1) because they are away by only 1 valence electron.
Reactivity generally increases from top to bottom in Group 1 elements due to the decrease in ionization energy. In contrast, Group 2 elements do not show the same reactivity trend as Group 1; reactivity generally increases from top to bottom due to the decreasing ionization energy, but other factors such as atomic size and electron shielding can also influence the reactivity patterns in Group 2.
As you go down Group 1 (alkali metals), reactivity increases due to the lower ionization energy, making it easier for these metals to lose their outermost electron. In contrast, Group 2 (alkaline earth metals) also shows an increase in reactivity down the group, but the trend is less pronounced compared to Group 1. This is because while ionization energy decreases, the presence of two outer electrons means that the reactivity is not solely dependent on losing one electron. Overall, both groups exhibit increasing reactivity down the group, but the rate of change is stronger in Group 1.
The reactivity of metals in groups 1 and 2 generally increases as you move down the group. This is due to the increasing ease with which the outermost electron can be lost to form positive ions.
The reactivity is increasing goinng down in the group.

The order of reactivity of alkaline earth metals decreases down the group. This means that the reactivity decreases as you go from beryllium to radium. Beryllium is the least reactive, while radium is the most reactive.
it is less common

As you move down Group 17 (halogens) from top to bottom, the reactivity decreases. This is due to the increasing atomic size and electron shielding, making it more difficult for the outer electron to be gained by the lower elements in the group, thus decreasing their reactivity.
Reactivity in group 1 of elements increases as we go down the group (to francium) because in the alkali metals as we go down the group number of atomic shells increases so the elements with most shells will easily release their electrons in the outer most shell.
The reactivity of metals in groups 1 and 2 generally increases as you move down the group. This is due to the increasing ease with which the outermost electron can be lost to form positive ions.

In terms of reactivity, Potassium(K) is the most reactive element among group 1 elements.
