Expert Answer

In terms of ionic compounds an oxide contains the oxide ion (O2-) which is a single oxygen atom with a 2- charge. In covalent compounds oxides are substances that contain oxygen in the 2- oxidation state and not bonded to other oxygen atoms.

Peroxide contains the peroxide ion  which is a particle of two oxygen atoms bonded together and has a 2- charge. Peroxides are good oxidizers. Peroxide contains a peroxide group in which each oxygen atom is bonded to the other oxygen and to another atom, typically carbon or hydrogen.

A superoxide contains the superoxide ion  which consists of two oxygen atoms bonded together and has a 1- charge. This ion is even more strongly oxidizing than the peroxide ion. In this case oxygen is in the 1- oxidation state.
