which of the following would NOT gain or lose electrons to form an ion with the same electron configuration as argon?AAluminumBCalciumCChlorineDSulfurwouldnt all of them gain or lose electrons??help thank you!
Because Argon is a Noble Gas, it does not have a Charge (+/-) Thus, all of the elements Al (3+), Ca (2+), Cl(-), and S(2-) would not be able to bond with Argon without losing an electron or gaining, etcThe answer is: Not possibleIt would've been E) None of the Above However, I think it may be Cl2 (because Chlorine occurs naturally as Cl2) and that it's electron configuration would be the same as ArgonBut at the same time, Cl2 is not an ionic compound, it's a moleculeNow that we have eliminated: Cl- and S2- (both would form a molecule), you only have 2 choices left: Calcium or Aluminum Now Calcium would seem more reasonable because it is a period under Argon - however, it must LOSE 2 electrons to end up as Argon's electron configurationIn order to have an element of the same electron configuration without losing/ gaining an electron: IT MUST BE THE SAME ELEMENT! _ The real answer is Argon.
