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 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.
Does nonmetal activity tend to decrease or increase as one goes down group 17?
Nonmetal activity tends to decrease as one goes down Group 17 (halogens) because the atomic size increases along the group, leading to weaker attraction for electrons and thus decreasing reactivity. Additionally, the atomic number increases which leads to increasing electron shielding and decreasing effective nuclear charge, reducing the tendency to gain electrons.
How reactive are halogens?
Halogens like fluorine, chlorine, bromine, iodine, and astatine are highly reactive elements due to their strong tendency to gain an electron to achieve a full outer electron shell. They readily form salts with metals and can react vigorously with other elements and compounds. Their reactivity decreases as you move down the group on the periodic table.
What is the pattern of reactivity observed in the non-metal elements in groups 13-17 of the periodic table?
The reactivity of non-metal elements generally decreases as you move from left to right across groups 13-17 of the periodic table. This is because the elements have an increasing number of valence electrons and are closer to achieving a stable electron configuration. Non-metals in group 17 (halogens) are the most reactive due to their high electronegativity and affinity for gaining electrons to achieve a full outer shell.
What functional groups are the most reactive?
Functional groups such as alkyl halides, acyl halides, and anhydrides are generally considered to be more reactive due to the presence of electronegative atoms (halogens, oxygen) that create polarized bonds, making them prone to nucleophilic attacks. Alkynes and alkenes are also reactive due to their ability to undergo addition reactions.
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?
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.
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.
Why does the reactivity increase down the group 7?
The reactivity of Group 7 elements (halogens) increases down the group because atomic size increases, leading to weaker bonding within molecules. This makes it easier for larger atoms to gain an electron to achieve a full outer shell, resulting in higher reactivity. Additionally, as the number of electron levels increase down the group, the elements are in a higher energy state, making them more reactive.

What happens to the reactivity of elements in a group labeled A as atomic numbers increase across period?
In a group labeled as A, as atomic numbers increase across a period, the reactivity of elements generally decreases. This is because as you move from left to right across a period, the elements have more protons in the nucleus, which leads to stronger nuclear charge and less tendency to lose electrons and react with other elements.
Which element in group 17 has the largest radius?
Iodine has the largest atomic radius in Group 17. This is because atomic radius tends to increase down a group on the periodic table, with iodine being located at the bottom of Group 17.
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?
The reactivity of non-metal elements generally decreases as you move from left to right across groups 13-17 of the periodic table. This is because the elements have an increasing number of valence electrons and are closer to achieving a stable electron configuration. Non-metals in group 17 (halogens) are the most reactive due to their high electronegativity and affinity for gaining electrons to achieve a full outer shell.
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.
Does nonmetal activity tend to decrease or increase as one goes down group 17?
Nonmetal activity tends to decrease as one goes down Group 17 (halogens) because the atomic size increases along the group, leading to weaker attraction for electrons and thus decreasing reactivity. Additionally, the atomic number increases which leads to increasing electron shielding and decreasing effective nuclear charge, reducing the tendency to gain electrons.
Is reactivity indicated by the position of the element?
Reactivity of an element is not directly indicated by its position on the periodic table. However, general trends can be observed - for example, elements in group 1 and group 17 tend to be highly reactive due to their tendency to gain or lose electrons, respectively.
What are the elements reactivity in group seven in the periodic table?
elements in group 17 need one more electron to attain the nearest noble gas configuration, hence they are more reactive
