Beryllium will lose 2 electrons to satisfy the octet rule (to fill its outer shell).
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.
The number of electrons in the outer shell of Beryllium is 2.
outer shell electrons are knows as Valence Electrons
Elements in the same group have the same number of valence electrons. These are the outer-shell electrons that react with other elements.
The valence electrons are involved in chemical bonding.
Beryllium has 2 outer shell electrons. Its full electronic configuration is:- 1s2, 2s2

The number of electrons in the outer shell of Beryllium is 2.
Beryllium has one valence shell containing two electrons.
The outer shell is called the valence shell

Valence Electrons
4V V-Valence Electrons Valence Electrons-Last electron (which is on the outer shell)
Beryllium has one outer electron shell with two electrons.
Elements in the same group have the same number of valence electrons. These are the outer-shell electrons that react with other elements.
The valence electrons
The valence shell is the outer most shell or imaginary orbit of an atom containing <8 electrons. The electrons in this shell are called 'valence electrons'.
