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.

Describe the Reactivity of group 1 element varies with increasing atomic number?
describe how the reactivity of group1 elements and group 7 elements varies with increasing atomic number
Does the reactivity of elements in group 2 increase going up or down?
The reactivity is increasing goinng down in the group.
Which element in 1a group is more reactivity?
fransium
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 does the reactivity of halogens change as you go down group 7?
dno
Describe the Reactivity of group 1 element varies with increasing atomic number?
describe how the reactivity of group1 elements and group 7 elements varies with increasing atomic number
Why do chemists use compounds instead of group 1 and 7 elements?
It is because the group 1 and 7 elements have a high reactivity. The reactivity is far too high to use on there own because the elements in these groups react with air and/or water.
How does the reactivity of group 1 metals change as you go down group 1?
The reactivity increase down in the group.
Alkali metal reactivity?
the reactivity increases as you go down the group
Does the reactivity of elements in group 2 increase going up or down?
The reactivity is increasing goinng down in the group.
Does the nitrogen group have high reactivity?
no
What is the reactivity group for chlorine?
Group one, the alkali metals
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.
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 is the relationship between an alkali metal and location in group 1A and its reactivity?
Th reactivity of alkali metals increases from the top of Group 1A to the bottom
What element group is the highest reactivity?
The halogen group, aka 7b or17.
