Beryllium Fluoride

    Can anyone explain to me why this is a molecule? The difference in electronegativity is larger than 2.0 on the Pauling scale - it should be ionic?

    Difference in electronegativity is only a rule of thumb, sometimes it fails.

    I'm curious. How did you determine that BeF2 is covalent? Did you use Fajan's Rule? If you did, you should look at the structure of BeF2 and think about dipole moments.
