Answer:
Copper (II) oxide
Explanation:
CuO consists of a transition metal and a non-metal. First, I name the metal as it appears on the Periodic Table, which is simply "Copper". Then, I write the name and charge of the non-metal, which in this case is, "Oxygen". Since it is ionic, I replace the "ygen" at the end, with "ide". Now, the name of CuO, so far, is Copper Oxide. Finally, I define its charge. Using prior knowledge, I know that oxygen has a -2 charge, and therefore, copper must have a charge of +2. To display that copper has a charge of +2, I put parentheses in between Copper & Oxide and wrote the Roman Numeral II in the parentheses. The final result is: Copper (II) Oxide.
(I know my answer isn't the best, but it seems to do the job. I just watched a video and followed along.)
