    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 :

    Name two metals which form amphoteric oxides.

    Which of the following alkali metals when burnt in air forms a mixture of oxide as well as nitride?

    On exposure to air, alkali metals get tranished due to formation of oxides, hydroxides and carbonates on their surface. When heated in air or oxygen they burn vigourously forming different types of oxides depending upon the nature of the metal. The formation and stability of these metals can be explained on the basis of size of alkali metal ion and the anion. Peroxides are colourless, while superoxides are coloured. The normal oxides are basic while peroxides and superoxides act as oxidising agents. Na_(2)O_(2) has light yellow colour. This is due to
