Preparation and reactions

It can be prepared by reacting beryllium metal with elemental bromine at temperatures of 500 °C to 700 °C:

Be + Br2 → BeBr2

Beryllium bromide is also formed when treating beryllium oxide with hydrobromic acid:

BeO + 2 HBr → BeBr2 + H2O

It hydrolizes slowly in water: BeBr2 + 2 H2O → 2 HBr + Be(OH)2

Safety

Beryllium compounds are toxic if inhaled or ingested.
