Properties of Copper oxide

Why is copper oxide insoluble in water?
Is copper Oxide ionically bonded?
ionic bonding is the bonding of ions
ions are atoms that have charges
so if you have bonding between metals and non-metals, you'll get a charged bond because one receives a negative charge (the electron) and the other gets its negativity taken away (via its election being transferred to the non-metal)
so ionic bonding is the bonding between metals and non-metals (i.e. copper oxide vis-a-vis copper and oxygen)

as for why it is insoluble in water, I can't even remember.

Thank you!
it's insoluble because it's not polar
