There are two forms of copper oxide: cuprous oxide and cupric oxide.

Cuprous oxide forms the colorful oxidation layer often seen on copper conductors exposed to weather or heat. If exposed to high heat, cupric oxide will form a black layer around the copper conductor.

Cuprous oxide is classified as a semiconductor, while cupric oxide is an insulator.

According to "Electrical connections: What you can do to prevent corrosion":

Copper oxide layers will reduce the number of contact points in a connection, thus increasing the contact resistance. Therefore, conductors should be cleaned prior to making a connection.

Electricity is the flow of electrons. Electrons move from one atom to the next adjacent atom. Electrons exist within shells at different distances from the nucleus of the atom. Copper has only one electron in it's outermost shell and therefore it is easy to strip the electron away and move it to the next atom, which simultaneously sheds it's electron. In addition, copper is very dense, meaning that the atoms are very compact...or close together to allow this transfer more freely.

There isn't much on the internet but from what I've read copper oxide isn't conductive because of the oxygen molecules.

Why does oxygen decrease the conductivity of copper?

Oxygen will make it impure and will react with the copper making it copper oxide, which isnt as conductive as copper alone


Does aluminum or copper produce more electricity?

Copper is more electrically conductive than aluminum (this is because aluminum forms a monomolecular layer of non-conductive aluminum oxide on its surface).


Is silver oxide conductive?

Silver is the best conductor of electricity. Following this is copper, gold and then aluminium.


What is the name for the compound Cu2O?

Copper (I) Oxide or Cuprous Oxide


What is the name of Cu2O?

CuO = Cupric Oxide Cupric = Cu2+ and is not Cu The correct answer would be CuO = Copper Monoxide Copper (II) oxide is the name of the compound CuO.
