Compounds that contain elements from Group 17 of the periodic table, which includes the halogens (fluorine, chlorine, bromine, iodine, and astatine), typically end with the suffix "-ide" when naming simple binary compounds. For example:
- NaCl is named sodium chloride.
- HBr is named hydrogen bromide.
In cases of polyatomic ions involving halogens, the naming conventions can vary. For example, when halogens form acids, the names might include "-ic" or "-ous" depending on the oxidation state of the halogen. For instance:
- HCl (when dissolved in water) is called hydrochloric acid.
Overall, the precise naming can depend on the type of compound being formed, but the general rule for simple binary salts is to use the "-ide" suffix.
