What is the correct name for NaBr?

The name for NaBr is sodium bromide. This compound is formed from the elements sodium (Na) and bromine (Br). In chemistry, sodium is an alkali metal that readily loses one electron to form a cation (Na⁺), while bromine is a halogen that gains an electron to form an anion (Br⁻). When these two ions combine, they create an ionic compound, NaBr, which is named by placing the name of the cation first (sodium) followed by the name of the anion with its ending typically changed to "-ide" (bromide).

In this context, sodium nitrate refers to NaNO₃, sodium chloride is NaCl, and sodium sulfide is Na₂S. These names correspond to different ionic compounds formed from other combinations of elements. Thus, sodium bromide accurately reflects the composition and structure of NaBr, distinguishing it clearly from the other options.
