group 17 or group 7 depending whether you're counting transition elements.
Group seven is known as the halogen group. The least reactive element in group seven is astatine. Fluorine is the most reactive.
The halogens are the highly reactive nonmetals on the periodic table. This group includes elements such as fluorine, chlorine, bromine, and iodine, which readily form compounds with other elements due to their strong tendency to gain an electron.
Group 17 elements, 'Halogens', have seven electrons in their valence shell and show the valency of 1. 4 of the 5 elements in that group are non metals including fluorine, which is the strongest.
The nonmetals in Group 7A are called halogens. They include elements such as fluorine, chlorine, bromine, iodine, and astatine. Halogens are highly reactive elements that tend to form salts when they react with metals.
The halogens are located in Group 17 of the periodic table, also known as the "halogen group." These elements include fluorine, chlorine, bromine, iodine, and astatine. They are highly reactive nonmetals with seven electrons in their outermost energy level.
Group seven on the periodic table refers to the halogens. This group includes fluorine, chlorine, bromine, iodine, and astatine. Halogens are highly reactive nonmetals that readily form compounds with other elements.
chemical properties due to their location in the same group (Group 17) of the periodic table. Both elements have seven valence electrons and tend to form similar types of compounds. Additionally, they are both highly reactive nonmetals.
