Reducing agents can be ranked by increasing strength by ranking their reduction potentials. Copper is considered a base metal as it is oxidized relatively easily, although it does not react with HCl. Can artificial intelligence replace teachers? Exposed to the oxygen in the air, it catches fire. An element that is oxidized is a reducing agent, because the element loses electrons, and an element that is reduced is an oxidizing agent, because the element gains electrons.
