The alkali metals which form normal oxide, peroxides as well as super oxides are :

Alkali metals form peroxides and superoxides except

Which alkali metal does not form peroxide and superoxide?

Alkali metals burn in air to form oxides, peroxides and superoxides. Lithium burns in moist air to form normal oxide as the major product. Some lithium nitride is also formed if nitrogen is present. Sodium loses lustre and forms both normal oxide and peroxide, the peroxide being the major product. Rest of all alkali metals form peroxides. All metals can be forced to form oxides, peroxides and superoxides by dissolving in liquid ammonia and bubbling appropriate amount of O_(2) . Which of the following oxides is the strongest oxidising agent :
