What is the charge of Copper?How do you determine it?
Copper has a Valence of 1 or 2 (1+ or 2+) as Copper (I) or Copper (II). 'NO3' has a Valence of 1 (1-). Copper (I) = Cu(1+) + NO3(1-) = CuNO3. Copper (II) = Cu(2+) + 2 x NO3(1-) in order to neutralise the 2+ of the Cu (II). = Cu(2+) + NO3(1-)x2 = Cu(NO3)2.
The charge of Cu, in this case, is +2. It can be deduced from the anion (NO3), which has a charge of -1. Since there are two NO3 anions, the total negative charge is -2. To make a neutral compound, the Cu must have a positive charge of +2. Generally speaking, it's easiest to calculate the oxidation state (i.e. charge) of metals from the anion they are associated with (at least in ionic compounds).

Copper (II) is copper with a +2 charge on the ion. To balance it you need 2 NO3- ions. When using the transition elements that may have more than one oxidation state, they need to tell you which you have.
