copper oxide

Could someone explain the bonding of copper oxide to me? What are each element's EC before and after?

Are you referring to Cu$_2$O (which is dark red) or CuO (which is black)?

Both. I don't understand either of them. When I am looking at this, should I consider their ECs by 2,8,8,8,8 etc or SPDF way? Do you know what each element's EC is before and after?

For basic understanding, a copper atom has electron counts 2, 8, 18, 1 and donates 1 valence electron in the case of Cu$_2$O or 2 valence electrons in the case of CuO.
