Identify the correct answer regarding  ${\mathrm{Na}}^{+}\& {\mathrm{F}}^{-}$

Ions are two types, they are Cation and Anion.A

Parent > Cation       Anion > Parent

$\mathrm{so} \mathrm{Na}>{\mathrm{Na}}^{+ } {\mathrm{F}}^{-}>\mathrm{F}$

$$\begin{gathered} \mathrm{In} {\mathrm{Na}}^{+} \mathrm{and} {\mathrm{F}}^{- } \mathrm{ions},{\mathrm{F}}^{- } \mathrm{has} \mathrm{larger} \mathrm{size} \mathrm{than} {\mathrm{Na}}^{+} \mathrm{the} \mathrm{reason} \mathrm{is} \mathrm{even} \mathrm{though} \mathrm{both} \mathrm{are} \mathrm{iso} \mathrm{electronic} \mathrm{species} \mathrm{the} \mathrm{ion} \mathrm{with} \mathrm{greater} \mathrm{atomic} \mathrm{number} \mathrm{has} \mathrm{smaller} \mathrm{in} \mathrm{size} \mathrm{than} \mathrm{the} \mathrm{ion} \mathrm{with} \mathrm{lower} \mathrm{atomic} \mathrm{number}. \\ {\mathrm{Na}}^{+}< {\mathrm{F}}^{- } \end{gathered}$$
