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.
You can describe the motion of an object by its position, speed, direction, and acceleration. An object is moving if its position relative to a fixed point is changing.

Is not a single replacement
<h3>Further explanation</h3>
A single replacement reaction is a chemical reaction in which one element replaces the other elements of a compound to produce new elements and compounds
Reactions
A+BC--> AC+B
Metal halogens can force metal halide ions in the order F> Cl> Br> I
Oxidation : F₂> Cl₂> Br₂> I₂
Reaction
NaBr+I₂ -> NaI+Br₂
Then the reaction will not occur because I₂ cannot oxidize Br, or the reaction is said to be non-spontaneous
