there are 54 electrons in Ba 2+. as the atomic no. of Ba is 56, so when it loses two of its electrons..
there are 54 electron left..

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.
The Lewis structure for a barium Ba ion looks like this Ba2 what best describes what happens when a barium atom forms an ion?
the barium atom loses two electrons
What is isoelectronic with Cesium?
Xe, Ba2+
What is the net ionic reaction for ammonium sulfate and barium chloride?

What would barium do to obtain a noble gas structure?
By losing two electrons to form Ba2+ ion.
When barium forms its most common ion it gains electrons?
No, it looses two electron and becomes Ba2+
Which changes occurs when a barium atom loses two electrons?
It becomes a positive ion and its radius decrease
Which is larger Ba or Ba2 plus?
Neither..they both have approximately the same weight as electrons are virtually weightless.bt the ba2 plus wud have to combine with another element for charge stability and the compound it forms shud be heavier than ba.
What is the correct electronic configuration for a ground state divalent Barium cation Ba2 plus?
[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].
What is the chemical formula for SO42- reacting with Ba2 plus?
Ba2(SO4)2
Ba2 exam datesheet in mdu rohtak?
exam date seet ba2
What is the difference between Ba and Ba 2 plus?
Ba2+ is the ion of the Ba atom. That means it has given away two electrons to other atoms in order to reach a stable state with 8 electrons in its outer shell.
How do you write Ba2 plus as a chemical equation?
This is not an equation but the chemical symbol of the cation: Ba2+.

What noble gas has the same electron configuration as Ba?
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).
