Reactions in chemistry are all about the number of electrons in the outer shell of an atom. Generally the more space it has in this shell the more reactive it will be.
Group 1 have only 1 electron in the outer shell, group 8 have 8 (8 is the maximum possible so these elements are not reactive).
Group 1 elements are highly reactive metals that readily form compounds to achieve a stable electron configuration. Group 7 elements (halogens) have high electronegativity and easily react with other elements to form compounds. This reactivity makes them commonly found as compounds rather than in their pure elemental form.
Pure elements in Group 1 (alkali metals) and Group 17 (halogens) are highly reactive due to their electron configurations. They readily form compounds with other elements to achieve a stable electron configuration. As a result, pure elements from these groups are not typically found in nature.
Group one elements are the most reactive with group 7 elements as it is the easiest way for the elements to complete their outer shell as the group one element gives its extra electron to the group 7 element and then the group 7 element has a full shell too.
Group 1 metals are very reactive because they have one electron in their outer shell, which they readily lose to achieve a stable electron configuration. Group 7 non-metals are very reactive because they are one electron short of a full outer shell, so they can easily accept an electron to achieve stability. This makes both group 1 metals and group 7 non-metals highly reactive in order to achieve a stable electron configuration.
Alkali metals from group 1 are very reactive and can easily react with air or moisture to form compounds. Halogens from group 7 are also highly reactive and tend to form compounds with other elements to satisfy their valence electron configuration. Therefore, it is more common to find them as compounds rather than in their free elemental form.

Group 1 elements are highly reactive metals that readily form compounds to achieve a stable electron configuration. Group 7 elements (halogens) have high electronegativity and easily react with other elements to form compounds. This reactivity makes them commonly found as compounds rather than in their pure elemental form.
Group 17 elements (group 7) become more reactive as you move down the group due to the increase in atomic size and shielding effects. As you go down the group from fluorine to iodine, the outermost electron shell gets farther from the nucleus, leading to weaker attraction, making it easier for the elements to gain an electron and become more reactive.

Pure elements in Group 1 (alkali metals) and Group 17 (halogens) are highly reactive due to their electron configurations. They readily form compounds with other elements to achieve a stable electron configuration. As a result, pure elements from these groups are not typically found in nature.
The group containing the most reactive elements is Group 1, also known as the alkali metals. These elements include lithium, sodium, and potassium, which are highly reactive due to their low ionization energies and tendency to lose electrons to form positive ions.
Group one elements are the most reactive with group 7 elements as it is the easiest way for the elements to complete their outer shell as the group one element gives its extra electron to the group 7 element and then the group 7 element has a full shell too.
Group 1 elements have very low electronegativies and group 7 elements have very high electronegativities, so that both are reactive with almost every other element, the group 1 elements by donating electrons and the group 7 elements by accepting electrons.
Group 7 elements are halogens. They have seven valance electrons& are highly reactive. They are: -Fluorine -Chlorine -Bromine -Iodine
For the most part, the Halogen group is the most reactive group on the periodic table. However, the Alkali metals are just as equal but not quite.
Group 1 metals are very reactive because they have one electron in their outer shell, which they readily lose to achieve a stable electron configuration. Group 7 non-metals are very reactive because they are one electron short of a full outer shell, so they can easily accept an electron to achieve stability. This makes both group 1 metals and group 7 non-metals highly reactive in order to achieve a stable electron configuration.
