Periodic TableIsoelectronic Species and Ionic Radius4Choose the best answerWhy is the ionic radius of S²⁻ larger than that of K⁺?AS²⁻ contains more electrons than K⁺.BK⁺ contains more occupied electron shells.CS²⁻ and K⁺ are isoelectronic, but S²⁻ has a lower nuclear charge.DS²⁻ has a higher nuclear charge than K⁺.
