  • Copper vs. Cuprous Oxide: What is the Difference?

    Jul 17, 2015 · When copper is exposed to water molecules (two hydrogen, one oxygen), this free electron is transferred to a neighboring oxygen atom, bonding it into a molecule. If only one atom of copper bonds to an oxygen molecule, it is called cupric oxide. If two copper atoms bond to an oxygen atom, it is cuprous oxide.
