CuCl2
Copper chloride is an ionic compound, specifically a metal halide.
CuCl2 is an ionically bonded compound; therefore, its minimum amount is preferably called a "formula unit" rather than a mole. Its gram formula unit mass is 134.45.
K[CuCl2]
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.
cuci2 is nothing. CuCl2 with a lowercase L is copper II chloride.
CuCl2
Copper(II) chloride is already a compound; its formula is CuCl2
Copper chloride is an ionic compound, specifically a metal halide.
CuCl2 is a compound or molecule with 3 atoms.
The compound is copper (I) perchlorate Cu(ClO4) The similar compound, copper (II) perchlorate is Cu(ClO4)2
CuCl2 is an ionic compound with two elements, copper and chlorine. Chlorine is a halogen, part of Group XVII, and copper is a transition metal, of Group XI.

Copper (II) Chloride
CuCl2 is an ionically bonded compound; therefore, its minimum amount is preferably called a "formula unit" rather than a mole. Its gram formula unit mass is 134.45.
In the chemical formula CuCl2 it is obvious for a neutral ionic substance that copper has a +2 charge, since Cl only comes in -1 charge, but in the stock name of copper chloride, it is unclear whether it is CuCl2 you are talking about or CuCl, which has a +1 Copper, thus in the name, the charge of the metal is differentiated by the roman numeral in parenthesis after the metal. This stock system (using numerals) is much easier to read than the previous traditional system of naming the higher charge metal with the -ic ending and the lower charged metal with the -ous ending, where CuCl2 and CuCl would be cupric chloride and cuprous chloride, respectively.
