Is bromine a single or double bond?

Bromine typically forms single bonds when it bonds with other elements, as it has seven valence electrons and tends to share one electron to achieve a stable octet. In its diatomic form (Br₂), bromine atoms are connected by a single bond. Double bonds can occur in certain compounds involving bromine, but they are less common. Overall, bromine is primarily associated with single bonds in its most common interactions.
