Halogens and Diatomic Molecules in Swimming Pools

The halogens are a group in the periodic table consisting of the five related elements of fluorine, chlorine, bromine, iodine and astatine. It's also known as Group 7.

Group 1 elements react with Group 7 elements to form, for example, lithium bromide.

Halogens all exist as diatomic molecules, so Chlorine exists as Cl2, Fluorine similarly, two halogen atoms joined by a covalent bond (where electrons are shared between atoms).
