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. Webbthan those of ions, most oxides are electronic conductors. One type of charge carrier often predominates in an oxide under particular conditions of temperature and oxygen pressure. An electronically conducting oxide is an n-conductor if transport of electrons predominate and a p-conductor if electron holes prevail.
