What is the correct name for NaBr?

The compound NaBr is composed of sodium (Na) and bromine (Br). In nomenclature, the naming of binary ionic compounds involves combining the name of the cation (positively charged ion) with the name of the anion (negatively charged ion). In this case, sodium is the cation and it retains its name, while bromine, being the anion, is named after its elemental root with an -ide suffix, resulting in "bromide."

Therefore, the correct name for NaBr is sodium bromide. This reflects the combination of the names of both ions present in the compound, aligning with standard rules for nomenclature in chemistry for ionic compounds.
