Vedclass · Answer

(B) Isoelectronic species are those species which have the same number of electrons.Total number of electrons in $O^{2-} = 8 + 2 = 10$.Total number of electrons in $Zn^{2+} = 30 - 2 = 28$.Total number of electrons in $Mg^{2+} = 12 - 2 = 10$.Total number of electrons in $K^{+} = 19 - 1 = 18$.Total number of electrons in $Ni^{2+} = 28 - 2 = 26$.Thus,$O^{2-}$ is isoelectronic with $Mg^{2+}$.

$O^{2-}$ is isoelectronic with
