Which family do the most active nonmentals belong to?

The most active nonmetals belong to the halogen family, which includes elements such as fluorine, chlorine, bromine, iodine, and astatine. Halogens are highly reactive due to their strong tendency to gain an electron to achieve a stable noble gas electron configuration. Among them, fluorine is the most reactive nonmetal. These elements are commonly found in nature in various compounds rather than in their elemental form.
