Question

li form monoxide,na peroxide and higher members form superoxide. why?​

Answer 1

Explanation:

Li does not seem to form a superoxide, LiO2, while Na does. ... This is why they so readily form in reactions of O2 with the alkali metals which only lose one electron from each atom. Superoxides are radical ions with 1 unpaired electron and are yellow in color while peroxides have no unpaired electrons.
