Beryllium (Be) has an atomic number of 4, which means it has 4 electrons in its neutral state. When beryllium forms a +2 ion (Be²⁺), it loses 2 electrons, resulting in 2 electrons remaining. Therefore, a beryllium ion (Be²⁺) has 2 electrons.
Beryllium has the electronic configuration 2, 2, so it is likely to lose two electrons, giving it the Helium configuration. However, in practice, beryllium compounds have a high degree of covalent character as the beryllium ion is small and very polarising.
Beryllium (Be) has a valence of +2. The ion could be written as (Be^2) or (Be+2) …
To draw and label the ion of beryllium, start with the symbol for beryllium (Be). Since beryllium typically loses two electrons to achieve a full outer shell, it forms a 2+ ion. So, the ion would be written as Be2+ and can be represented as [Be]^2+.
The formula for a beryllium ion is Be2+. This indicates that the beryllium atom has lost 2 electrons, resulting in a 2+ charge.
A beryllium ion, like Be2+, has lost two electrons compared to a neutral beryllium atom. A neutral beryllium atom has 4 electrons, with 2 in the inner shell and 2 in the outer shell. When it loses 2 electrons to become Be2+, it now has 2 electrons remaining, both in the inner shell.
Beryllium has the electronic configuration 2, 2, so it is likely to lose two electrons, giving it the Helium configuration. However, in practice, beryllium compounds have a high degree of covalent character as the beryllium ion is small and very polarising.
Beryllium is element 4, so the "neutral" atom would have 4 protons and 4 electrons. In order to have a "-2" charge, it would need 6 electrons.
Beryllium will lose 2 electrons when forming an ion because it has 4 valence electrons and tends to reach a stable electron configuration by losing electrons to achieve a full outer shell.
Beryllium cation, or Be2+, is a positively charged ion of beryllium that has lost two electrons. Beryllium anion, or Be2-, is a negatively charged ion of beryllium that has gained two electrons. Both ions are formed to achieve a stable electron configuration by either losing or gaining electrons.
Beryllium (Be) has 4 protons and 4 electrons in its neutral state. When it forms the Be2+ ion, it loses two electrons, leaving it with 4 protons and 2 electrons. The Be2+ ion has a 2+ charge because it has lost two negatively charged electrons.

The Fe2 ion has 4 unpaired electrons.

You question is a bit incorrect. Beryllium is a metallic element in Group (II) of the Periodic Table. Being in Group (II) it will have a strong tendency to loose electrons(ionisation). In its neutral state beryllium has the electron structure of 1s2, 2s2, This means that its inner most electron shell (1s) contains two electrons. Its outer most electron shell (2s) also contains two electrons. When beryllium ionises two electrons , they are 'lost' from the outer most (2s) electron shell. They are further from the nucleus of the atom and are not so strongly held.!!!!! When these two electrons have 'gone' , the Beryllium atom is now the Beryllium ION. (It is no longer an atom). Formulaically it is written as Be(g) = Be^(2+) + 2 e^(-) So for beryllium atom to become a Beryllium ION it LOSES TWO electrons.
A beryllium ion, like Be2+, has lost two electrons compared to a neutral beryllium atom. A neutral beryllium atom has 4 electrons, with 2 in the inner shell and 2 in the outer shell. When it loses 2 electrons to become Be2+, it now has 2 electrons remaining, both in the inner shell.
