Copper (II) Oxide or Cupric Oxide
Since copper(II) oxide is an ionic compound, the Cu+2 and the O-2 stick together due to electrostatic attraction. This type of bond is very similar to a magnetic bond.
Since some metallic elements form cations that have different positive charges, the names of ionic compounds from these elements must show indication of the cation charge. Use of the suffixes -ous and -ic to denote the lower and higher charges, respectively. In the cases of iron and copper, the Latin names of the elements are used (ferrous/ferric, cuprous/cupric), the name of the anion ends in -ide.
