Beryllium will lose 2 electrons to satisfy the octet rule (to fill its outer shell).
An octet is 8 electrons- but even 2 electrons are okay for achieving stability. A beryllium atom has 2 shells, with 2 electrons in each shell. Since it is a metal, it will lose electrons instead of gaining them, forming a positively charged ion. This means that it will lose both the electrons in its outermost shell, leaving it with a single shell containing 2 electrons. So, basically beryllium loses 2 to electrons to form a stable duet with a charge of 2+! Hope this helped you (:
Beryllium has 4 electrons.
In the ion of barium, two electron are lost to follow the octet rule (to have a complete valence electron shell).
Beryllium has the electronic configuration 2, 2, so it is likely to lose two electrons, giving it the Helium configuration. However, in practice, beryllium compounds have a high degree of covalent character as the beryllium ion is small and very polarising.
