Li → oxide (Li₂O) Na → peroxide (Na₂O₂) K, Rb, Cs → superoxide (MO₂)................. Cesium (Cs) forms superoxide most readily because its large Cs⁺ ion stabilizes the large superoxide ion (O₂⁻) better..............between K and Cs, the answer is Cs, because the larger Cs⁺ ion stabilizes the large O₂⁻ ion more effectively.
