WebbMetals that conduct electricity by the flow of electrons are called metallic conductors. It’s just about physical changes, and conductivity decreases with increasing temperature. … WebbSolution (c) Certain metal oxides like V O2, V O, V O3, and T iO3 show metallic or insulating property depending upon temperature. As temperature varies metallic or insulating property varies. This is due to a variation in the energy gap between the conduction band and valence band. Suggest Corrections 1 Similar questions Q. 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. birthplace shakira
