What is Copper Oxide? (with pictures)
Sep 27, 2019· There are two oxides of copper because it can bond with nonmetals by donating either one or two electrons. Oxygen forms compounds with metals by gaining two electrons, so it can accept one electron from each of two copper atoms — forming copper(I) oxide — or two electrons from one atom — forming copper(II) oxide.
