Bromine gas, consisting of two bromine atoms bonded together.
Conjugate Acid (Br₂ + H⁺ -> 2HBr): When Br₂ accepts one proton, it becomes two molecules of HBr as its conjugate acid.
Conjugate Base (Br₂ -> 2Br⁻): When Br₂ donates one proton, it forms two bromide ions as its conjugate base.
A compound formed when bromine reacts with sodium, resulting in an ionic salt.
