Beryllium will lose 2 electrons to satisfy the octet rule (to fill its outer shell).
It is a Group 2 element, therefore it has two outer-shell electrons. To gain a full outer-shell, it loses two electrons to form a cation (cations are positive ions)
The outer shell number for beryllium is 2. Beryllium has 4 electrons, so in its electron configuration, 2 electrons are in the first energy level and 2 electrons are in the second energy level, making the outer shell number 2.
Electrons are found in an atom's outer shell. The outer shell, also known as the valence shell, is where the electrons involved in chemical reactions and bonding are located. The number of electrons in the outer shell determines the atom's chemical properties.
The beryllium atom has 4 electrons and the valence is 2.
No. Carbon has 4 electrons in its outer shell (valence shell).
Beryllium has 2 outer shell electrons. Its full electronic configuration is:- 1s2, 2s2
The outer shell is called the valence shell

Beryllium has one valence shell containing two electrons.

Valence Electrons
Beryllium has one outer electron shell with two electrons.
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'.

valence electrons are the electrons on the outer-most shell of electrons
