Name the alkali metals which form superoxides when heated in excess of air.

Which metal will not form superoxide-

Assertion : Generally alkali and alkaline earth metals form superoxides. Reason : There is single bond between O and O in superoxides.

Among the following which metal forms superoxides of type MO_2 ?

What kind of oxides are formed by sodium?

What kind of oxides are formed by sodium?

Lithium only forms monoxide when heated in oxygen. Sodium forms monoxide and peroxide in excess of oxygen. Other alkali metals form superoxide metals superoxide with oxygen i.e., MO_(2) . The abnormal behaviour of lithium is due to small size. The larger size of higher metals also decides the role in formation of superoxide. All the three anions abstract proton from water. The three anions are raleted to each other as follows: underset("oxide ion")(O_(2)^(2-)overset((1)/(2)O_(2))(to)underset("peroxide ion")(O_(2)^(2-))overset(O_(2))(to)underset("superoxide ion")(2O_(2)^(-)) Q. Consider the following reaction : M+O_(2) to MO_(2) (M=alkali metal) (stable superoxide)
