In which group of the periodic table are halogens found?

Halogens are found in Group 17 of the periodic table. This group is characterized by elements that are highly reactive nonmetals, including fluorine, chlorine, bromine, iodine, and astatine. The reactivity of halogens is due to their electronegativity and their tendency to gain one electron to achieve a stable electron configuration, similar to the noble gases.

In Group 17, halogens display a range of physical and chemical properties, such as being diatomic molecules in their elemental form (e.g., Cl₂, F₂) and forming salts when they react with metals. Understanding the location and characteristics of halogens is essential in chemistry, especially when discussing reactions with other elements and compounds.
