There are actually two forms of copper oxides. And as pointed out in
(as I remember it) a further post the green patina is not from the
oxide, but from the effects of sulphides on the oxide after it has
formed. It must be true because that's what Wikipedia says. :-)
It could be sulfides or it could be a combo of water and carbon dioxide.
The green looks like Malachite, a copper carbonate-hydroxide.
