the reactivity of halogens goes on decreasing as we go down the group, because of increasing in atomic size of the respective element.
What else can I help you with?
Does halogens reactivity decreese as you mov down the group?
Nope.
Describe how the reactivity of Group 7 Halogens changes as you move down the column Explain why this happens?
The reactivity of Group 7 halogens decreases as you move down the column from fluorine to iodine. This is because atomic size increases down the group, leading to weaker intermolecular forces of attraction between atoms. As a result, it becomes harder for the halogens to gain an extra electron and they become less reactive.
Why does reactivity of the halogens decrease down the group?
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 reactivityDEcreases down the group of NON-metals which gain stronger their electrons andINcreases down the group of metals which loose those electrons.
What happens to the reactivity nonmetals as you move down a period?
The reactivity is increasing, from left to right - for example halogens.
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.

As a result, it becomes harder for the halogens to gain an extra electron and they become less reactive.
How does the reactivity of halogens change as you go down group 7?
As you go down group 7 (halogens), reactivity decreases. This is because as you move down the group, the outer electron shells of the halogens are further away from the nucleus, making it harder for them to gain an electron and react with other elements. Additionally, the atomic size increases which leads to weaker intermolecular forces between the atoms.
Does halogens have high or low reactivity?
Halogens have high reactivity because they have a strong tendency to gain an electron to achieve a stable electron configuration. This reactivity decreases as you move down the group from fluorine to iodine.

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.
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.
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 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.
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.
