I can put a case, the data without the special mention for normal temperature (25 degrees Celsius), the ordinary pressure (100 kPa).

Beryllium (beryllium bromide) bromide is bromide of beryllium expressed in BeBr₂. Absorbency is very good and dissolves in water well.

Reaction

I can get beryllium bromide by reacting bromine of the simple substance and metal beryllium at the temperature of 500 degrees Celsius - 700 degrees Celsius. ^[1]:

Be + Br₂ → BeBr₂

I can get beryllium bromide by reacting beryllia and a hydrobromic acid (liquid) or a hydrogen bromide.

BeO +2 HBr → BeB_r2 + H₂O

Safe

Or an intake is harmful when I inhale it.
