Why does the reactivity of the group 17 increase as you go down the group?

that's because....
group 1 (e.g Na, K) those tend to lose one electron to gain noble gas electron configuration.
they can achieve that by just losing one electron from their outer shell.
as you go down the group 1, element gets bigger in size, which means there is more space between nucleus (which is in center of atom) and electron of outer shell. the more far away they are the less attraction force between them.
so its easier for potassuim to lose one electron than for lithuim.
so that means potassium will easily give up 1 electron to react with non metal or other element therefore it is more reactive than lithuim
but in case of non metal, the opposite happens but simple to understand.
as you go down the group 7 (halogen- Cl, Br, I) element will get bigger therefore force between nucleus and outer electron is getting smaller. they have to gain 1 electron in order to fill the outer shell (to gain noble gas electron configuration.)
as florine is more smaller in size than clorine it is more reactive because florine has more tendency to pull extra electron from metal or other element towards its side. so it easily gain 1 electron to react.
....
its very simple once you understand....

∙ 13y agoBecause:
1. The electronegativity decreases downward in both column, because there are more inner electrons shielding the outer shell to which an electron could be added from the attractive force of the nucleus.
2. The usual effect of reaction of elements in column 1 is to lose an electron, which is more energetically favored when electronegativity is low, while the usual effect of reaction of elements in column VII is to gain an electron, which is more energetically favored by high electronegativity.

∙ 13y agoYes. Reactivity increases as you go down every group. except for group 7

Group 7A nonmetals react by gaining an electron. The electron affinity generally decreases going down the group. This trend parallels chemical reactivity.

What functional groups are the most reactive?
The Group 1 and Group 17 elements are the most reactive. Group 1 is the Alkali metals, and their reactivity increases going down the column. Group 17 is the Halogens, and their reactivity increases going up the column.this is not answering the question. The question asks which ORGANIC Functional group (amine, ketone, etc.) is the most reactive, not which group on the periodic table.
What is the reactivity of group 7?
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.
What is the pattern of reactivity observed in the non-metal elements in groups 13-17 of the periodic table?
Reactivity of non-metals increases as you move from left to right on the periodic table, or as group number increases. The most reactive non-metals are found in group 17.
How reactive are halogens?
In the periodic table, the reactivity of the halogens that are found in Group 17 decreases as you go down the column of elements in this group. The first element of the group is fluorine, and it has the highest reactivity. The other elements in this group are chlorine, bromine, iodine, and astatine.
Does nonmetal activity tend to decrease or increase as one goes down group 17?
It's decrease because florine has the most activity.
As the elements in Group 17 are considered in order of increasing atomic number the chemical reactivity of each successive element decreases increases or remains the same?
The chemical reactivity decreases in group 17 as you go down the group.
What functional groups are the most reactive?
The Group 1 and Group 17 elements are the most reactive. Group 1 is the Alkali metals, and their reactivity increases going down the column. Group 17 is the Halogens, and their reactivity increases going up the column.this is not answering the question. The question asks which ORGANIC Functional group (amine, ketone, etc.) is the most reactive, not which group on the periodic table.
How do you tell the reactiveness of a non metal on the periodic table?
The periodicity of nonmetals is that reactivity increases from left to right across a period, through group 17, the halogens. As you move down a group, reactivity decreases. Fluorine is the most reactive element.

What happens to the reactivity of elements in a group labeled A as atomic numbers increase across period?
they become more reactive since you are moving from left to right on the periodic table, the elements in group 17 are the most reactive.
What happens to the reactivity of elements in groups as the atomic numbers increase across a period?
they become more reactive since you are moving from left to right on the Periodic Table, the elements in group 17 are the most reactive.
What is the pattern of reactivity observed in the non-metal elements in groups 13-17 of the periodic table?
Reactivity of non-metals increases as you move from left to right on the periodic table, or as group number increases. The most reactive non-metals are found in group 17.
Why does the reactivity increase down the group 7?
The reactivity decreases down group 7. Group 7 elements have 7 valence electrons (electrons on the very last electronic shell), so this means it need to attract one electron (because its harder to lose 7 than attract 1) to attain stable electronic configuration of 8 electrons. Now because atomic radii decreases down a group, the nucleus is further away from the electrons, and the further away they are, the lower the force of attraction, making it harder to form a bond, meaning, they react less readily. Volia! Reactivity decreases down group 7. This is also the reason why reactivity increases down group 1 Because there is 1 valence electron, it needs to lose 1 electron to attain stable electronic configuration (because its harder to attract 7 than lose 1) and because the atomic radii decreases down a group (this rule is constant through the entire periodic table) the attraction is weaker, so its easier to lose 1 electron, making it easier for group 1 to bond, meaning, they react more readily.
What happens to reactivity of elements in groups labeled a as atomic numbers increase across a period?
they become more reactive since you are moving from left to right on the Periodic Table, the elements in group 17 are the most reactive.
How do the radii for anions and cations change as you go down a group?
In the groups 1-5 and 12-17 atomic radius increase down in group.In groups 6-17 the variation is irregular.

How reactive are halogens?
In the periodic table, the reactivity of the halogens that are found in Group 17 decreases as you go down the column of elements in this group. The first element of the group is fluorine, and it has the highest reactivity. The other elements in this group are chlorine, bromine, iodine, and astatine.
