How many valence electrons does barium have?
There are 2 valence electrons in Barium.
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 general valence shell configuration for the elements in group 1A?
Valence electron configuration in group 1A: ns1 in which n=1, 2, 3, 4, 5, ... etc. Starting with Hydrogen, H, electron configuration: 1s1 followed by Lithium, Li, electron configuration: (1s2), 2s1 (non valence electrons in () brackets)
Which pair of atoms will have the same valence-shell electron configuration Se and Te Sr and Cs N and O H and He?
Se and Te will have the same valence-shell electron configuration as they are both in the same group (group 16) and have 6 valence electrons. Sr and Cs will have different valence-shell electron configurations as Sr is in group 2 with 2 valence electrons and Cs is in group 1 with 1 valence electron. N and O will have different valence-shell electron configurations as N has 5 valence electrons while O has 6. H and He will have different valence-shell electron configurations as H has 1 valence electron and He has 2.
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 valence shell electron configuration of silver?
one electron in the 5s orbital
How many valence electrons does barium have?
There are 2 valence electrons in Barium.
How many electrons are gained or lost in barium?
In the ion of barium, two electron are lost to follow the octet rule (to have a complete valence electron shell).
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.
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 general valence shell configuration for the elements in group 1A?
Valence electron configuration in group 1A: ns1 in which n=1, 2, 3, 4, 5, ... etc. Starting with Hydrogen, H, electron configuration: 1s1 followed by Lithium, Li, electron configuration: (1s2), 2s1 (non valence electrons in () brackets)
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.
Which pair of atoms will have the same valence-shell electron configuration Se and Te Sr and Cs N and O H and He?
Se and Te will have the same valence-shell electron configuration as they are both in the same group (group 16) and have 6 valence electrons. Sr and Cs will have different valence-shell electron configurations as Sr is in group 2 with 2 valence electrons and Cs is in group 1 with 1 valence electron. N and O will have different valence-shell electron configurations as N has 5 valence electrons while O has 6. H and He will have different valence-shell electron configurations as H has 1 valence electron and He has 2.

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 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 does the electron configuration of an atom reveal?
It can reveal the number of valence electrons in the last shell.
