$O_2$

Vedclass · Answer

(A) The electronic configuration of $O_2$ ($16$ electrons) is: $KK (\sigma 2s)^2 (\sigma^* 2s)^2 (\sigma 2pz)^2 (\pi 2px)^2 (\pi 2py)^2 (\pi^* 2px)^1 (\pi^* 2py)^1$. It has $2$ unpaired electrons.The electronic configuration of $O_2^+$ ($15$ electrons) is: $KK (\sigma 2s)^2 (\sigma^* 2s)^2 (\sigma 2pz)^2 (\pi 2px)^2 (\pi 2py)^2 (\pi^* 2px)^1$. It has $1$ unpaired electron.The electronic configuration of $O_2^-$ ($17$ electrons) is: $KK (\sigma 2s)^2 (\sigma^* 2s)^2 (\sigma 2pz)^2 (\pi 2px)^2 (\pi 2py)^2 (\pi^* 2px)^2 (\pi^* 2py)^1$. It has $1$ unpaired electron.The electronic configuration of $O_2^{2-}$ ($18$ electrons) is: $KK (\sigma 2s)^2 (\sigma^* 2s)^2 (\sigma 2pz)^2 (\pi 2px)^2 (\pi 2py)^2 (\pi^* 2px)^2 (\pi^* 2py)^2$. It has $0$ unpaired electrons.Thus,$O_2$ has the maximum number of unpaired electrons.
