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
Chloride ion in AlCl3 has a charge of -1. The compound AlCl3 is aluminum chloride, which is an inorganic compound that can react with water.
Its a Compound ( which is when two ions bond and form 'one' atom/compound) with a charge - Its a Compound ( which is when two ions bond and form 'one' atom/compound) with a charge -
The charge on a chloride ion in any ionic compound is -1. AlCl3 is usually considered an ionic compound, although it has some covalent character in its bonds also. If the compound is considered covalent, the characteristic number for a particular atom within the compound is usually called "oxidation number" or sometimes "formal charge" instead of simply "charge", but that is also -1.
+2 oxidation state
copper (II) fluoride
Copper(II) nitrate. The Roman numeral indicates the charge of the copper ion.
Since Oxygen has an ion charge of -2 & Copper has a 2 as a subscript, it means that Copper's ion charge will be +1. Cu2O = Copper (I) Oxide
This compound is copper(II) nitrate.

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.
Cyclohexane has no charge. It is a compound, not an ion.
First, you need to determine the elements in the equation. They are copper and fluorine, respectively. Next, we determine if the compound is ionic or covalent. Remember that a basic ionic cmpd is a metal bonded to a nonmetal, and a basic covalent compount is non-metal-non-metal. Copper is a metal, so the bond is ionic. To name an ionic compound, you have the first part (the metal) written regularly, and the second part (in this case a monoatomic non-metal) is written regularly, but the last part is dropped and replaced with "ide". So far, the name of our compound is Copper fluoride. There is a certain type of metal called a transition metal. These metals, unlike the alkali or alkaline earth metals, have no set charge. Therefore, we must determine copper's charge and indicate it in the name. Balancing the charges: fluoride has a -1 charge. There are two F ions, making the charge of the non-metals -2. The charge must be balanced to 0, which can be done using thie following equation: x + -2 = 0 --> add 2 to both sides, the twos cancel on the right, and we get x = 2. Therefore the charge of the copper ion is 2+. To indicate this in the name, you put the charge in roman numeral form in parenthesis after the metal. The final name is Copper (II) fluoride.
A copper ions has a positive charge, most commonly 2+.

There is no iron ion in SCl3. The charge on the scandium ion is 3+.
As there are two of them, the charge on the copper ion is 1+ to balance the charge of the oxygen (2-).
