Preparation and reactions
It can be prepared by reacting beryllium metal with elemental bromine at temperatures of 500 °C to 700 °C:
Be + Br2 → BeBr2Beryllium bromide is also formed when treating beryllium oxide with hydrobromic acid:
BeO + 2 HBr → BeBr2 + H2OIt hydrolizes slowly in water: BeBr2 + 2 H2O → 2 HBr + Be(OH)2
Safety
Beryllium compounds are toxic if inhaled or ingested.
