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 else can I help you with?
Why the trend in reactivity of group 7 elemnts is the opposite to the trend in group 1?
The trend in reactivity of Group 7 elements (halogens) is opposite to that of Group 1 elements (alkali metals) due to their differing electron configurations and tendencies to gain or lose electrons. Group 1 elements have one electron in their outer shell and readily lose it to achieve a stable electron configuration, making them highly reactive. In contrast, Group 7 elements have seven electrons in their outer shell and tend to gain an electron to complete their octet, which makes them more reactive as you move up the group. Therefore, while reactivity increases down Group 1, it increases up Group 7.
Does the reactivity of elements in group 2 increase going up or down?
The reactivity is increasing goinng down in the group.
What is a group 7 compound?
A group 7 compound refers to a chemical compound that contains an element from group 7 of the periodic table, which is also known as the halogens group. This group includes elements such as fluorine, chlorine, bromine, iodine, and astatine. Group 7 compounds are known for their reactivity and tendency to form salts.
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.
Describe the Reactivity of group 1 element varies with increasing atomic number?
The reactivity of Group 1 elements increases with increasing atomic number. This is due to the fact that as atomic number increases, the outermost electron is farther away from the nucleus, making it easier to lose and therefore more reactive. Additionally, the size of the atom increases down the group, leading to a weaker attraction between the outermost electron and the nucleus, further enhancing reactivity.
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.
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.

A group 7 compound refers to a chemical compound that contains an element from group 7 of the periodic table, which is also known as the halogens group. This group includes elements such as fluorine, chlorine, bromine, iodine, and astatine. Group 7 compounds are known for their reactivity and tendency to form salts.
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.
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

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 does reactivity change from top to bottom in group1 does the same pattern hold in group2?
Reactivity generally increases from top to bottom in Group 1 elements due to the decrease in ionization energy. In contrast, Group 2 elements do not show the same reactivity trend as Group 1; reactivity generally increases from top to bottom due to the decreasing ionization energy, but other factors such as atomic size and electron shielding can also influence the reactivity patterns in Group 2.
