Quizplus · Accepted Answer

Ionic radius increases with increasing number of electrons (for anions) and decreases with the loss of electrons (for cations). Here, K+ has lost an electron, making it the smallest. Cl-, S2-, and P3- have gained one, two, and three electrons respectively, increasing their sizes in that order.
