Vedclass · Answer

(D) The species $F^{-}$,$Ne$,and $Na^{+}$ are isoelectronic,as each contains $10$ electrons with the electronic configuration $1s^2, 2s^2, 2p^6$.Since they have the same number of electrons,the variation in their ionic/atomic radii is determined by the nuclear charge $(Z)$.As the nuclear charge increases (from $F^{-}$ to $Ne$ to $Na^{+}$),the force of attraction between the nucleus and the electrons increases,leading to a decrease in size.

In case of isoelectronic species,the size of $F^{-}$,$Ne$,and $Na^{+}$ is affected by:
