WebbAnswer. An oxide is a chemical compound that contains the element oxygen. The oxygen in a compound will be bonded to one another element, creating a binary compound. For example, when copper metal reacts with oxygen gas, copper (II) oxide ( C u O) is formed. An oxide, therefore, contains at least one atom of oxygen. Webb11 juni 2016 · 5 Answers.
