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 else can I help you with?
How many core electrons does a barium atom have?
Barium has 56 eletrons56 electrons and protons.
Number of electrons present in a neutral barium atom?
A neutral barium atom has 56 electrons. This is because the atomic number of barium is 56, which represents the number of protons and electrons in a neutral atom.
How many electrons are present in a neutral barium atom?
A neutral barium atom has 56 electrons. This is because the atomic number of barium is 56, which corresponds to the number of electrons it has when it is electrically neutral.
The Lewis structure for a barium Ba ion looks like this Ba2 what best describes what happens when a barium atom forms an ion?
When a barium atom forms an ion, it loses two electrons to achieve a stable octet configuration like a noble gas. This results in the formation of a Ba2+ ion with a 0 oxidation state.
A barium atom attains a stable electron configuration when it bonds with?
A barium atom attains a stable electron configuration when it bonds with a halogen atom, such as chlorine, by transferring one of its valence electrons to achieve a full outer shell. This results in the formation of an ionic bond between the two atoms.

Barium has 56 eletrons56 electrons and protons.
How many valence electrons does an atom of barium possess?
A barium atom has two valence electrons.
Number of electrons present in a neutral barium atom?
A neutral barium atom has 56 electrons. This is because the atomic number of barium is 56, which represents the number of protons and electrons in a neutral atom.
The atom whose electron configuration ends in 5s2 is?
The atom with an electron configuration ending in 5s2 is Barium (Ba), a chemical element with atomic number 56. In its ground state, Barium has two electrons in the 5s orbital.
How many electrons are present in a neutral barium atom?
A neutral barium atom has 56 electrons. This is because the atomic number of barium is 56, which corresponds to the number of electrons it has when it is electrically neutral.
What are the number of electrons present in a neutral barium atom?
The barium atom (neutral) contain 56 electrons.
The Lewis structure for a barium Ba ion looks like this Ba2 what best describes what happens when a barium atom forms an ion?
When a barium atom forms an ion, it loses two electrons to achieve a stable octet configuration like a noble gas. This results in the formation of a Ba2+ ion with a 0 oxidation state.
How many electrons does Baruim have?
Barium's atomic number is 56. Thus, an atom of barium has 56 protons in it. To keep it electrically neutral then, a barium atom must also have 56 electrons per atom.
A barium atom attains a stable electron configuration when it bonds with?
A barium atom attains a stable electron configuration when it bonds with a halogen atom, such as chlorine, by transferring one of its valence electrons to achieve a full outer shell. This results in the formation of an ionic bond between the two atoms.
When a barium atom forms its most common ion it?
When a barium atom forms its most common ion, it loses two electrons to achieve a stable octet configuration, resulting in a 2+ ion with a charge of +2.
