copper (II) fluoride
This compound is copper(II) nitrate.
Cu^2+
The electron configuration of a Copper(II)ion is [Ar]4s0 3d9.
As there are two of them, the charge on the copper ion is 1+ to balance the charge of the oxygen (2-).
Copper metal "dissolves" in nitric acid (HNO3). Actually, the nitrate ion oxidizes the copper metal to copper (II) ion while itself being transformed to NO2 gas in the process; the copper (II) ion then binds to six water molecules.

Copper (II) Sulfate, is an ionic compound. If that is what you are asking. Anytime you have a metal that has a number in parenthesis after it, you're going to be using ions. The number in paranthesis is what indicates the charge on the ion. For example, Copper (II) would have a charge of +2.
The electron configuration of a Copper(II)ion is [Ar]4s0 3d9.
Copper(II) nitrate. The Roman numeral indicates the charge of the copper ion.
As there are two of them, the charge on the copper ion is 1+ to balance the charge of the oxygen (2-).
The electron configuration of copper(II) is [Ar] 3d9 . Copper is [Ar] 3d10 4s1
CuCl02 is Copper Chlorite. Cu is Copper, and Cl02 is Chlorite
copper (I) carbonate The carbonate ion has a -2 charge. Since the formula given is Cu2CO3, it indicates there are 2 Cu atoms required to fulfill the carbonate ion's needs. This means the Cu ion must be of the Cu+1 species.
