Vedclass · Answer

(A) All the given species are isoelectronic,meaning they all have $18$ electrons.$Cl^{-}: 17 	ext{ protons}, 18 	ext{ electrons}$$Ar: 18 	ext{ protons}, 18 	ext{ electrons}$$K^{+}: 19 	ext{ protons}, 18 	ext{ electrons}$$Ca^{2+}: 20 	ext{ protons}, 18 	ext{ electrons}$For isoelectronic species,the ionic radius decreases as the nuclear charge (number of protons) increases,because the electrons are pulled more strongly towards the nucleus.Since $Cl^{-}$ has the lowest number of protons $(17)$,it experiences the weakest effective nuclear charge,resulting in the largest ionic radius.

Of the following,the one with the largest size is:
