A rather simple question, but I'm hoping for some follow- up if an answer is given.

not really, no.if it was you'd expect it to form a positive and a negative ion. You might be able to get copper 1- ions if you put it with cesium (gold does that), but i'd hardly say it's amphoteric.

 

it might have amphoteric oxides though...

Actually Cu(OH)2 is mildly amphoteric!

But not regular Cu.

Check out these this link too, if you scroll down to the section there is discussion about sodium curprate solutions which are more amphoteric than carbonate!
