These elements are diatomic molecules in their natural form. They require one more electron to fill their outer electron shells, and so have a tendency to form a singly-charged negative ion. |

Many synthetic [organic compounds]?, and a few natural ones, contain halogen atoms; these are known as halogenated compounds. |
The group of chemical elements in group VIIA of the Periodic Table; specifically Fluorine, Chlorine, Bromine, Iodine, and Astatine. These elements are diatomic molecules in their natural form.
