I hope that helps!
Halides (the negative halogen atom) are named like many other anions, with a -ide suffix.
For example, a fluorine atom forms a fluoride, a chlorine atom forms a chloride, and a bromine atom forms a bromide.
The link in Ani E's answer above looks like a great resource if your just getting started with the nomenclature for halogens inside of organic molecules.
Hope this helps!!!
