Bromine wikipedia
Bromine compounds are compounds containing the element bromine (Br). These compounds usually form the -1, +1, +3 and +5 oxidation states. Bromine is intermediate in reactivity between chlorine and iodine, and is one of the most reactive elements. Bond energies to bromine tend to be lower than those to chlorine but higher than those to iodine, and bromine is a weaker oxidising agent than chlorine but a stronger one than iodine. This can be seen from the standard electrod… WebJakob Brøchner Madsen.

WebIt can be prepared by reacting beryllium metal with elemental bromine at temperatures of 500 °C to 700 °C: [1] Be + Br 2 → BeBr 2. Beryllium bromide is also formed when treating beryllium oxide with hydrobromic acid : BeO + 2 HBr → BeBr 2 + H 2 O. It hydrolyzes slowly in water: BeBr 2 + 2 H 2 O → 2 HBr + Be (OH) 2.
