As it go down the group, the distance between the nucleus (+ve) and the last electron (-ve) becomes smaller No: BIGGER.
Therefore the electrons are held in the atom very tightly more loosely by a strong weakening force from the nucleus.
So, it is said as the reactivity
- DEcreases down the group of NON-metals which gain stronger their electrons and
- INcreases down the group of metals which loose those electrons.

∙ 9y agoThe general reactivity of halogens decreases down the group due to the increase in the number of filled electron shells. Hence the attraction between nucleus and electrons decreases down the group. Because of its inability to accept electrons, the reactivity decreases while moving down the group.

∙ 13y agoThe reactivity of halogens decreases with increasing atomic size as one goes down the Periodic Table column that contains the halogens. This happens because halogens react primarily by abstracting electrons from less electronegative atoms, and the attraction for additional electrons is stronger when there are fewer filled elctron shells between the valence electrons and the atomic nucleus.

What happens to the reactivity of halogens as you go down the group?
the reactivity of halogens goes on decreasing as we go down the group, because of increasing in atomic size of the respective element.
Does halogens reactivity decreese as you mov down the group?
Nope.
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 the reactivity of elements in group 2 increase going up or down?
The reactivity is increasing goinng down in the group.
Why melting point decrease down the group for Alkali metals but increase for Halogens?
Because the atomic radius increases down the group 1 and decreases down the group of halogen

How does the reactivity of halogens change as you go down group 7?
dno
How chemically active are halogens?
Very, tho reactivity decreases down the group
What can you say about reactivity of the halogens as you go down the group from fluorine to astatine?
Reactivity decreases. In other words, fluorine is the most reactive of the halogens while astatine is the lease reactive. This is because the ability to attract electrons(electronegativity) decreases as you go down the group.
What is the most reactive halogen?
the halogens decrease in reactivity as you move down the group, so i guess that the least reactive would be Astatine. Hope this helps =)
What halogen is most likely to react?
The reactivity of halogens decreases down the group, which means Fluorine is the most reactive halogens as it is the most electronegative elements among the halogens, and also 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.
How does the reactivity of group 1 metals change as you go down group 1?
The reactivity increase down in the group.
Does the reactivity of elements in group 2 increase going up or down?
The reactivity is increasing goinng down in the group.
Why melting point decrease down the group for Alkali metals but increase for Halogens?
Because the atomic radius increases down the group 1 and decreases down the group of halogen
