2+
Copper can have a +1 charge, known as cuprous ion, and a +2 charge, known as cupric ion. These charges depend on the oxidation state of copper in a compound.
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
the II means that the charge of the copper, in this case, is +2, rather than, say, +1, which is copper's other possible charge. the formula for copper II chloride is CuCl2, rather than copper I chloride, which is simply CuCl. for all transition metals which have multiple charges, it is necessary to state the particular charge thet the atom is using.
When a copper ion bonds with chlorine, it bonds with 2 chlorine atoms, because copper has a charge of 2+ (?? cf. Added answer below) and chlorine a charge of 1-So to balance each other, the final formula is CuCl2 one copper ion to two chloride ions. The overall charge on any ionic bond is 0. They bond because they balance each other.Added:Cuprous chloride (Cu(I)-chloride) is sparingly soluble in water, but very soluble in concentrated hydrochloric acid as a complex ion of CuCl2-, in which Cu is +1 charged, and Cl has -1 charge. The white solid crystal is CuClOn Cupric chloride (Cu(II)-chloride) there are many more possible complex ions. for this you are referred to the 'Related links' left below this answer page.
I'm not sure. But my wife had a college professor who pronounced cation as "cay-shun" instead of "cat-ion" and called anions "an-yuns" instead of "an-ions." How that person got a PhD without ever learning ot say basic words is beyond me...
The name of CuF2 in the Stock system is copper(II) fluoride.
The formula for cupric fluoride is CuF2. Another name for this compound is copper(II) fluoride.
The charge on the copper ion in Cu3P is +1. This is because the overall charge for the compound Cu3P is 0, and since there are three copper ions present, each copper ion must have a charge of +1 to balance the -3 charge of the phosphorus ion.
The compound is copper(II) oxide, which has a chemical formula CuO. In this compound, copper is in the +2 oxidation state, giving it a charge of 2+.
Copper can have a +1 charge, known as cuprous ion, and a +2 charge, known as cupric ion. These charges depend on the oxidation state of copper in a compound.
Copper(II) chlorate is an ionic compound. In this compound, the copper ion has a charge of +2 and the chlorate ion has a charge of -1. The ions attract each other through ionic bonds, where electrons are transferred from the copper atom to the chlorate 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
The charge on copper ion (Cu^2+) and iron ion (Fe^3+) in the compound Cu3FeP would be +2 and +3 respectively.
The chemical formula for copper(I) bromide is CuBr. It is a compound that contains one copper ion with a +1 charge and one bromide ion with a -1 charge.
When copper combines with oxygen to form copper oxide, the copper ion has a +2 charge. This is because copper typically forms a 2+ oxidation state when it combines with oxygen in this compound.
Copper(II) nitrate. The Roman numeral indicates the charge of the copper ion.
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
