Beryllium is the fourth atomic number of the periodic table. The symbol of Beryllium is “Be” and it is a very rare element which is found in the universe. Usually, this element occurs as the product of the separation of the larger atomic nuclei which are collided with the cosmic rays.
Electronic configuration can be defined as the distribution of the electrons in the atomic shells of the atoms or molecules. In the case of Beryllium, there are 4 electrons which are present in the 2 orbits of its atom.
The electronic configuration of Beryllium is: 1s22s2 or can also be represented as [He] 2s2.
What is The Electron Configuration of Beryllium
The electronic configuration of beryllium is the distribution of its 4 electrons in the shells of the atom and it can be represented as 1s22s2
How Many Valence Electrons Does Beryllium Have
Valence electrons can be defined as the number of electrons present in the outer most shell of the atom. In the case of beryllium, there are 2 electrons present in the second or outer most shell. So, a number of valence electrons of beryllium are 2.
Beryllium Number of Valence Electrons
A number of valence electrons in beryllium is 2. As the electrons located in the outer most orbit is considered as valence electrons and beryllium has 2 electrons in its outer shell.
