+2 oxidation state for the Copper.
-1 for the Chloride
Simple halide ions always have an oxidation number of -1. Therefore, in this compound copper must have an oxidation number of +2 to achieve electrical neutrality for the compound.
+2 oxidation state
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.
Copper can exist in two states of oxidation.The oxidation state of Cu in CuCl2 (cupric chloride) is +2 and that of Cl- is -1.However,the oxidation state of Cu in CuCl (cuprous chloride) is +1 and that of Cl- is -1.
With the oxidation state being II for copper. CuBr2
CuCl2
Cupric is used when copper is in a +2 oxidation state while cuprous is used when copper is in a +1 oxidation state.

A Roman number in the name of an ionic compound gives the absolute value of the oxidation number of that element in the compound which immediately precedes the Roman number. This is most common with cations of elements, such as copper and cobalt, that can form stable cations in more than one oxidation state. Copper(II) chloride, for example as the formula CuCl2 while copper(I) chloride has the formula CuCl.
With the oxidation state being II for copper. CuBr2
Copper (III) chloride. Note that this is theoretical compound copper does have a +3 oxidation stae in some complexes but does not from compounds such as CuCl3. The only halides known are +1 oxdtn state:- CuCl, CuBr, CuI +2 oxdtn state : CuF2, CuCl2, CuBr2
The problem with your question is that "Copper chloride" is not a chemical formula; it is the name of a chemical compound. However, I understand what you are asking. The problem with the name "copper chloride" is that it is ambiguous. One must be able to write an unambiguous chemical formula from the compound's name and vice versa, but that cannot be done here since "copper chloride" can be either CuCl or CuCl2.Oxidized copper exists either as Cu+1 or as Cu+2. In other words, the copper atom has lost either one or two electrons. "Chloride" is chlorine with a -1 formal charge, thus it takes either one or two chloride ions to create [the neutral compound] copper chloride.For metal ions, the name of the ion with the highest oxidation state has the suffix "-ic" and the ion with the lower oxidation state possesses the suffix "-ous." That means that copper chloride is actually either cupric chloride, CuCl2, or it is cuprous chloride, or CuCl.

There are two different copper chloride compounds, due to the two possible 'oxidation state numbers' (+1 and +2):CuCl cuprous chloride, Cu(I) chloride, mono-valent Copper chlorideCuCl2 cupric chloride, Cu(II) chloride, bi-valent Copper chloride

+2 oxidation state
CuCl2
Copper II chloride (CuCl2) is an ionic compound because copper is a metal and chloride is a non-metal. Like all ionic compounds in aqueous solutions (i.e., dissolved in water), it conducts electricity.
