Q33.The increasing order of the ionic radii of the given isoelectronic species is : (1) Cl−, Ca2+, K+, S2− (2) S2−, Cl−, Ca2+, K+ (3) Ca2+, K+, Cl−, S2− (4) K+, S2−, Ca2+, Cl−
What This Question Tests
This question tests the knowledge of trends in ionic radii for isoelectronic species, specifically how increasing positive charge decreases size and increasing negative charge increases size due to varying effective nuclear charge.
