In an electrically neutral atom, the number of electrons is the same as the number of protons. Since the number of protons is the atomic number of an atom, and Beryllium has an atomic number of 4, this means that Beryllium has 4 protons in its nucleus. As mentioned previously, if the atom is electrically neutral, then Beryllium will also has 4 electrons.
Beryllium has 4 electrons in its chemically stable state. When it's combining with other substances, many people only consider the valence electrons (Beryllium has 2) or the outermost electrons. The number of valence electrons is most easily recognized based on the Group number of that element (excluding the transition metals). Group one has one valence electron and Group 7 has seven valence electrons.

Electronic configuration of beryllium: 1s2.2s2.
The electron configuration of beryllium (Be) is 1s22s2.
The valence electrons of beryllium are two.
2 electrons in its outer shell
Be (beryllium) has four electrons total: the first orbital, the 1s orbital, has two, which leaves two electrons in the outer shell.
Beryllium is a stable element.
Magnesium is a metal element. There are 12 electrons in a single atom.
4 protons 4 electrons 5 neutrons
Beryllium should be expected to have a charge of 2+ as is expected of all the elements in Group 2 of the periodic table. But its behavior is somewhat different than other Group 2 elements because it has so few electrons. This element tends to form covalent bonds.All nuclei have a positive charge.So beryllium-9 has a positive charge.
Beryllium has one outer electron shell with two electrons.
Beryllium and magnesium have two electrons in their outermost energy level, as do all Group 2 elements.
Electronic configuration of beryllium: 1s2.2s2.
Beryllium will lose 2 electrons to satisfy the octet rule (to fill its outer shell).
There are 2 electrons in the inner level, 8 electrons in the middle level, and exactly 6 electrons in Sulfurs outer level.
Be (beryllium) has four electrons total: the first orbital, the 1s orbital, has two, which leaves two electrons in the outer shell.
Boron has 3 electrons in it's outer level.
7Fluorine has 7 electrons in the outer level.
2 because it has two outer shell electrons out of 8 (relevant rule only for the first 20 elements)
10 electrons
Nitrogen has 5 electrons in its outer shell, and Bromine has 7 electrons in its outer shell.
Two electrons
