Solution

The correct option is C $T i^{+}$
Number of electrons in $O^{2 -} = 8 + 2 = 10$
Number of electrons in $N^{3 -} = 7 + 3 = 10$
Number of electrons in $F^{-} = 9 + 1 = 10$
Number of electrons in ${N a}^{+} = 11 - 1 = 10$
Number of electrons in ${T i}^{+} = 22 - 1 = 21$

$∴ {T i}^{+}$ is not isoelectronic with $O^{2 -}$
