Ionic bonding part 2

Another example of ionic bonding is the blending of Beryllium and Fluorine to form beryllium fluoride.
Beryllium has 2 outer electrons and as stated before metals will lose their outer electrons to obtain a full outer shell. Since fluorine needs to gain 1 electron to complete its outer shell and Beryllium needs to lose 2 electrons, one Beryllium atom will bond with 2 Fluorine atoms:

The transfer of electrons from beryllium results in the formation of an ionic bond. Beryllium now has a positive (+2) charge and Fluorine now has a negative charge. The resulting compound is called Beryllium Fluoride (BeF2).
