It depends on the compound.
+1 and +2 are the more common ones (as in Cu2I2 and CuI2 respectively).
In elemental form, its oxidation number is zero.

Is the oxidation number of copper 3 positive?
3+
What is the oxidation number of copperII?
+2 for Copper(II)
What is oxidation number of Cu?
If the question is Cu2, then it is equivalent to Cu and the oxidation number for any element is zero. If the question is Cu2+, then the oxidation number is +2.
What is the oxidation number of copper in copper iodide?
+1 in CuI or Cu2I2. +2 in CuI2.
What are the oxidation numbers of copper CuCl?
Oxidation number is the charge per atom in a compound. Cl2= 2- (Cl= 1-) Cu would have to be 2+ to balance the compound, because there is only one copper atom.
How many oxidation number does copper have?
4. They are +1, +2, +3, +4. The +1 and +2 oxidation numbers are the best known.
What are three elements that have more than oxidation number?
Common examples include many nonmetals as sulfur which bears oxidation numbers varying from -2 to +6 in forming compounds. In oxychlorides, the oxidation number of chlorine atom(s) vary from -1 to +7. Many transition elements also bear different oxidation numbers. Copper has two ions: Copper(I) which is colorless and Copper(II) which is pale blue.
