Lithium being very small in its group forms only oxide. It does not form peroxide. If it forms oxide the formula will be Li2O (oxidation state of oxygen is -2) while for peroxide state at drastic condition the formula will be Li2O2(oxidation state of oxygen is -1). In oxide there is direct bond between metal and oxygen while in peroxide –O-O- linkage will be present and metals are attached at the adjacent points.
