The halogen family, also known as Group 17, consists of the following elements:

- Fluorine (F)

- Chlorine (Cl)

- Bromine (Br)

- Iodine (I)

- Astatine (At)

- Tennessine (Ts) (synthetic element)

These elements are known for their high reactivity and their tendency to form salts with metals. They are all diatomic molecules, meaning they exist as pairs of atoms bonded together. Halogens are also highly electronegative, meaning they have a strong tendency to attract electrons.
