When the isoelectronic species, K+, Ca2+, and Cl-, are arranged in order of increasing radius, what is the correct order?
K+ , Ca2+, Cl–
K+ , Cl– , Ca2+
Ca2+, K+ , Cl–
Cl– , Ca2+,K+

As given ions are isoelectronic species , their radii would be inversely proportional to the atomic number. So, Calcium has the least radius. Potassium will have more than Calcium and less than Chlorine.
