Beryllium has two electron shells.
The number of electrons in the outer shell of Beryllium is 2.
Electronic configuration of beryllium: 1s2.2s2. Two electrons on each shell.
Beryllium will lose 2 electrons to satisfy the octet rule (to fill its outer shell).
The beryllium atom has 4 electrons and the valence is 2.
Beryllium has atomic number 4, so 4 protons. The electronic configuration 1s2 2s2 has 2 electrons in the 1s shell and 2 electrons in the 2s shell, which is 4 electrons.
The number of electrons in the outer shell of Beryllium is 2.
The number of electrons in the element Be (Beryllium) are 4. 2 in the first shell and 2 in the outer shell.hope I helped
