What is group 7 on the periodic table?

Answer 1

Group 7 on the Periodic Table is known as the halogens, which includes the elements fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). These elements are highly reactive nonmetals and are known for forming salts when combined with metals. Halogens typically exist as diatomic molecules (e.g., F₂, Cl₂) in their elemental form and exhibit varying physical states at room temperature—fluorine and chlorine are gases, bromine is a liquid, and iodine is a solid. Their reactivity decreases down the group, with fluorine being the most reactive.
