A simple anion (obtained from a single atom) is named by taking the root of the parent element's name and adding the suffix -ide. Thus, the F − ion is called fluoride, Br − is called bromide, S 2− is called sulfide, and so on. The following examples illustrate the nomenclature rules for binary ionic compounds: compound.

This result illustrates that the formation of black stannous and stannic oxides was mainly attributed to the existence of bromide from CTAB. Wei et al.
