Why does barium form an ion with a charge of 2 plus?

Barium forms an ion with a 2+ charge because it has 2 valence electrons in its outer shell. By losing these 2 electrons, barium achieves a stable electron configuration similar to a noble gas, which is energetically favorable.


What is the condensed ground state electron configuration for Barium?

The condensed ground state electron configuration for Barium is [Xe] 6s^2. This indicates that Barium has a full inner electron shell (represented by the noble gas configuration of Xenon) and two electrons in the outermost 6s orbital.


How many electron does barium have to give up to achieve a noble gas electron configuration?

Two electrons


How many electons does barium have to give up to achieve a noble -gas electron configuration?

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.


What is the electron configuration difference of Co and Co2 plus?

Cobalt electron configuration is [Ar]3d7.4s2.Cobalt(2+) electron configuration is [Ar]3d7.


How many electrons does barium have to give up in order to achieve a noble gas electron configuration?

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.


What is the number of outer rings dose barium has?

The electron configuration of barium is [Xe]6s2.Barium has six electron shells with 2, 8, 18, 18, 8, 2 electrons.


How many electrons must a barium atom lose to form an ion with noble-gas 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.


What type of ion would barium form if group 1 loses one electron to form ions with a 1 plus charge?

Barium is in group two of the periodic table. Based on the information known for group one, it can be predicted (correctly) that barium will lose two electrons to form an ion with a plus 2 charge. Thus, the resulting ion in reactions of barium is Ba2+.


How many electrons does barium has to give up to achieve a noble gas electron configuration?

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.


What is the electron configuration of the barium ion?

barium has a 2+ chage so u would add 2 electron to take away that chage. 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6


How many electrons do barium need to lose to become stable?

Barium, with an atomic number of 56, needs to lose 2 electrons to achieve a stable electron configuration, similar to a noble gas. This is because barium will then have a filled outer electron shell, following the octet rule.
