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.

Elemental copper (Cu) is in oxidation state '0'.
The copper cation can exhibit two oxidation states, they are +1 & +2
In oxidation state +1 it forms cuprous sulphide ( Cu2S)
In oxidation state +2 it form cupric sulphide (CuS)
NB THere are other compounds of copper exhibiting these oxidation states.

What is the oxidation number in Cu2S?
Cu = +1
What is the oxidation number of CuF2?
Cu is +2 and F is -1
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.
What is the oxidation number of cuco3?
+2 for Cu, +4 for C, -2 for O
What is the oxidation number of CuFeS2?
cu =1+ fe=3+ s=2-
What is the oxidation number in Cu2S?
Cu = +1
What is the oxidation number of Cu as a product?
The oxidation of any element, by itself, is zero.
What does the oxidation number of an element tell you?
The oxidation number tells you the "combining power" of that element. For example, if Cu has a 1+ oxidation number then it will combine with Cl in a 1:1 ratio, and result in CuCl. If Cu has an oxidation number of 2+, then it will combine with Cl in a 1:2 ratio, and result in CuCl2.
What is the oxidation number of CuF2?
Cu is +2 and F is -1
What are the oxidation numbers of copper CuCl?

Is Cu oxidized or reduced in CuO plus H2 yields Cu plus H2O?
Cu is oxidized. The oxidation number goes from 0 in Cu to +2 in CuSO4. S is reduced. The oxidation number goes from +6 in H2SO4 to +4 in SO2. The oxidizing agent is H2SO4 since it causes Cu to be oxidized. The reducing agent is Cu since it causes S in H2SO4 to be reduced.
Which of these metals has the hardest oxidation Cu Al Fe or Cr?
Cu
What is the oxidation number of CuHSO4?
+1 for Cu, +1 for H, +6 for S, -2 for each O
