You can tell that the beryllium atom is unstable because beryllium only has 2 valence electrons in its outer shell. An atom becomes stable when it has eight valence electrons, so in the case of beryllium it would have to lose those 2 electrons in its outer shell to become stable. often forming a cation with a 2+ charge.

Which would you most expect to be an unstable atom?
Any atom in the first family of the periodic table of elements is very unstable.
What is the name of a beryllium ion?
Beryllium (Be) has a valence of +2. The ion could be written as (Be^2) or (Be+2) …
How many electrons are in a beryllium ion?
The beryllium atom has 4 electrons. As with all other elements, Beryllium atoms are most stable when they have a full outer shell of electrons. Since the neutral electron configuration of the beryllium element atom is 1s2 2s2 (total of 4 electrons) the atom either needs to pick up another six electrons, thereby becoming 1s2 2s2 2p6, or lose two electrons to become 1s2.
