Which group do halogens react with the most?

Group 2 because it consists of cations.

Group 16 because that group is next to the halogens and consists of anions.

Group 1 because they have one valence electron that the halogens need to be stable.

Group 18 because that is the group next to the halogens.

Group 1 because they have one valence electron that the halogens need to be stable.

The correct answer is Group 1 because they have one valence electron that the halogens need to be stable. Halogens are highly reactive nonmetals that have seven valence electrons and are looking to gain one electron to achieve a stable electron configuration. Group 1 elements, also known as alkali metals, have one valence electron that they are willing to donate to halogens, resulting in a stable electron configuration for both. This is why halogens often react with Group 1 elements to form ionic compounds.

The correct answer is Group 1, also known as the alkali metals. Halogens are highly reactive nonmetals, and they have a tendency to gain one electron to complete their outermost energy level and become stable. Group 1 elements, on the other hand, have only one valence electron, which they are eager to lose in order to attain a stable electron configuration. This makes them highly reactive as well. When halogens react with Group 1 elements, they tend to gain the electron from the alkali metals, resulting in the formation of an ionic compound. Hence, Group 1 elements are the group that halogens react with the most.
