In general, beryllium has a tendency to bond covalently, much more so than the other alkaline earths and its fluoride is partially covalent (although still more ionic than its other halides).
Generelt har beryllium en tendens til at binde kovalent, meget oftere end de andre jordalkalimetaller, og dets fluorid er delvist kovalent (selv om det stadig er mere ionisk end dets andre halidforbindelser).
