To tell if BeF2 (Beryllium
To tell if BeF2 (Beryllium fluoride) is ionic or covalent (also called molecular) we look at the Periodic Table that and see that is a metal and is a non-metal. When we have a metal and a non-metal the compound is usually considered ionic.
⭐ However ...
BeF2 is an exception to the general rule because of the small size of the Be 2+ ion. Therefore, even though there is a considerable amount of ionic character, BeF2 is usually considered to be an covalent compound.

Because we have a combination of a non-metal and non-metal BeF2 (Beryllium fluoride) is considered an covalent/molecular compound.
In general, covalent compounds compounds:
- have low melting points and boiling points.
- have low enthalpies of fusion and vaporization.
- do not conduct electricity when dissolved in water.
