$Ar^{+}$

Vedclass · Answer

(D) Key point: Species with one or more unpaired electrons exhibit a non-zero magnetic moment.Electronic configurations:$Na^{+} (Z=11) = 1s^{2} 2s^{2} 2p^{6}$ (All electrons paired)$Mg (Z=12) = 1s^{2} 2s^{2} 2p^{6} 3s^{2}$ (All electrons paired)$F^{-} (Z=9) = 1s^{2} 2s^{2} 2p^{6}$ (All electrons paired)$Ar^{+} (Z=18) = 1s^{2} 2s^{2} 2p^{6} 3s^{2} 3p^{5}$ (One unpaired electron in $3p$ orbital)Since $Ar^{+}$ has an unpaired electron, it possesses a non-zero magnetic moment. Therefore, $(d)$ is the correct option.

Which of these species will have a non-zero magnetic moment?
