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.
+2 oxidation state for the Copper. -1 for the Chloride
In CuCl2, the oxidation state of copper (Cu) is +2, and the oxidation state of chlorine (Cl) is -1. This is because the overall charge of the compound is 0, and there are two chloride ions each with an oxidation state of -1 to balance the +2 charge of copper.
CuCl2 is a type II compound. In type II compounds, the cation can have multiple oxidation states, and the charge of the cation must be determined from the compound's formula. CuCl2 contains copper in the +2 oxidation state.
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.

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.
CuCl2 is a type II compound. In type II compounds, the cation can have multiple oxidation states, and the charge of the cation must be determined from the compound's formula. CuCl2 contains copper in the +2 oxidation state.
The formula name for CuCl2 is copper(II) chloride. It indicates that copper is in its 2+ oxidation state in the compound.

The formula for copper(I) chloride is CuCl, and the formula for copper(II) chloride is CuCl2. In copper(I) chloride, copper has a +1 oxidation state, while in copper(II) chloride, copper has a +2 oxidation state.
The Roman numeral following the cation tells you the oxidation number of that cation. For example, Cu(ll)chloride tags you it is CuCl2 because the (ll) after Cu indicates an ox. no. of 2+.
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.
Hydrogen's oxidation number is +1.Chlorin's oxidation number is +1.Oxygen's oxidation number is -2.
The formula for copper(I) chloride is CuCl, where copper has a +1 oxidation state. The formula for copper(II) chloride is CuCl2, where copper has a +2 oxidation state.
