They are the anions of the halogen elements.

Explanation:

A halide is any ion that is originally a halogen. Halogens are group 7 or 17 on the periodic table. They are very reactive elements, and will oxidize anything just to get that extra electron, in the case of fluorine.

Halides are anions of halogens. Some halides include chloride (Cl^-), fluoride (F^-), and bromide (Br^-) just to name a few.

They will also readily combine with other elements to make compounds, such as the common hydrochloric acid in the lab, which consists of one hydrogen cation (a proton) and one chlorine anion (chloride). It has a chemical formula of HCl.

Once a halide has gained that extra electron, it becomes much less reactive, and some halides become less harmful to human health, such as the case of fluoride ions, that are present in our toothpaste.
