When barium becomes an ion, it typically loses two electrons to achieve a stable electron configuration, resulting in a barium ion with a charge of +2. This ion is represented as Ba²⁺. The loss of these two electrons allows barium to attain the same electron configuration as the nearest noble gas, xenon.
Barium has two electrons in its outermost shell (the 6s subshell) and typically loses these two electrons to achieve a stable electron configuration, resembling that of the nearest noble gas, xenon. Therefore, barium needs to give up two electrons to achieve this stable state. As a result, it commonly forms a +2 oxidation state in compounds.
There is no noble gas with the same electronic configuration as the element barium (Ba). But Ba2+ ion and the noble gas xenon (Xe) will have the same number of electrons (54 electrons each).
As Barium's atomic number is 56 and as it has 2 electrons in its outer shell (this is also due to the fact that it is in Group 2) its valency is 2. It loses 2 electrons to attain the electronic configuration of Xenon whose atomic number is 54, so it is electropositive and is a metal.Therefore its valency is 2+.

Barium (Ba) has an atomic number of 56, meaning it has 56 electrons. The electron configuration for barium is [Xe] 6s², indicating that it does not have any electrons in the 5p subshell. Therefore, barium contains 0 electrons in the 5p subshell.
Barium has 2 electrons in its outer shell. In order to achieve a noble gas electron configuration it needs to lose these 2 electrons. This will leave it with the same electron configuration as Xenon, a noble gas.
The formula for the barium ion is Ba^2+. It has lost two electrons to achieve a full outer shell and a stable electronic configuration.
Two electrons are donated by Barium to an oxidant (nonmetal, eg. O2) by which barium gets oxidised.Ba --> Ba2+ + 2e-This is because Ba is in group 2 of the periodic system, belonging to the 'earth alkali' metals and so it has 2 electrons (2e-) in its valency (or outer) shell (2,8,18,18,8,2). Hence Ba2+ configuration is (2,8,18,18,8,-), with an empty (-) 6th shell (the 'P' shell) like Xenon.
Barium has 2 valence electrons. It needs to give up these 2 electrons to achieve a noble gas electron configuration, specifically by having a filled outer shell like a noble gas.
Two electrons
[Xe] Normally the electronic configuration for Barium would be [Xe] 6s2, but since you want it for Ba2+, you're missing two electrons. You get rid of the 6s2 and get [Xe].
Barium has 2 electrons in its outermost shell. To achieve a noble gas electron configuration similar to xenon, which has 8 electrons in its outermost shell, barium would need to give up 2 electrons. This would leave barium with a full outer shell and a stable electron configuration.
When barium becomes an ion, it typically loses two electrons to achieve a stable electron configuration, resulting in a barium ion with a charge of +2. This ion is represented as Ba²⁺. The loss of these two electrons allows barium to attain the same electron configuration as the nearest noble gas, xenon.
Barium loses two electrons in a reaction, so it becomes positive or a cation.
Barium has 0 unpaired electrons. It's a diva that likes to keep things balanced with 56 electrons total. So, no need to worry about any lonely hearts club in its electron cloud.
