* Bromine is a liquid at room temperature. Unlike metals or other elements that form solid minerals, bromine is a liquid. It exists primarily as bromide ions dissolved in water.
* Bromide minerals are rare. While some bromide minerals do exist (e.g., bromargyrite, AgBr), they are relatively rare and not the primary source of bromine.
* Bromine is extracted from brines. The vast majority of bromine is commercially extracted from brines (salty water) found in underground deposits or in seawater.
Therefore, it's more accurate to think of bromine's occurrence as being in dissolved form rather than as a primary or secondary mineral.
