The charge of a copper ion is +2 ....>> or +1 (this is a more abundant oxidation state)
Added:- In Cu2O the ion charge is Cu1+, (cuprous oxide, Cu(I) oxide, oxidation state +1) color brownish red (or yellow, depending on how fine the particles are)
- In CuO the ion charge is Cu2+, (cuprous oxide, Cu(II) oxide, oxidation state +2) color black
The charge carriers in all of the well-known layered copper oxide high-temperature superconductors1- are holes located in the CuO2planes, the common structural element of these systems. Recently, Tokura et al.5 have reported that doping of Ln2CuO4, where Ln represents Pr, Nd or Sm, with formally tetravalent Ce can produce a high-temperature superconductor with electron carriers. To determine the character of the carrier states in Nd2-xCexCuO4, we have performed X-ray absorption measurements at the Cu K and Ce L3 edges for several different Ce concentrations. We find clear evidence that the electrons introduced by doping fill 3dholes on the Cu atoms, thus converting some Cu2+ ions to Cu+. Hence the nature of the states nearest to the Fermi energy (that is, those responsible for conduction) is qualitatively different from that in the hole-doped superconductors, in which the holes move in a band formed predominantly from O 2p states8-10. As a result, the details of the electron-pairing mechanism could be very different in the two systems11.
The charge of copper in Cu is typically +2. However, copper can also exist in other oxidation states such as +1.
Copper normally is neutral but it can form ions with a 1+ or a 2+ charge.
+2 maybe ?
Copper there is 2 different types depending on the formula it is being used in:
it is either 2+ or 3+
Charge of elemental copper (metal, Cu) is zero, neutral.
Ions of Cu can be either 1+ (cuprous, Cu(I)) or 2+ (cupric, Cu(II)).

What is the molecular formula of copper acetate?
Copper ethanoate in solution consists of two parts: Ethanoate ion: CH3-(COO)- (to note this has a negative charge on the COO represented by the - and a bond after CH3 also represented by a -) This has only single bonds from both oxygens to the carbon, the charge is then spread across the two oxygens and the carbon making the molecule polar and soluble Copper ion: Cu2+ ions have a 2+ charge and so are in solution (generally anything with a charge will be in solution) When this is dehydrated the copper ethanoate is formed as a precipitate using 2 ethanoate ions and 1 copper ion to give a charge of 0 throughout the molecule. The formulae of this is Cu(CH3COO)2 and for some reason i cant get subscript and superscript to work on this so you will have to assume its there.
What is the standard notation for copper?
The standard notation for copper is Cu.
What is the chemical symbol for copper?
Copper has Cu as its chemical symbol.
What is the atomic symbol for copper?
Cu, which is derived from the Latin word for copper, cuprum.
What is the formula of copper 2 nitrite?
It generally refers to Copper(II) nitrate: Cu(NO3)2
What is the charge of copper cu?
The charge of copper (Cu) can vary depending on the specific compound it is part of. In its most common form in nature, copper typically has a charge of +2.
What is the charge for CuO?
The charge for CuO is +2. The copper (Cu) ion has a charge of +2, while oxygen (O) has a charge of -2. This results in a neutral compound when combined.
What is the formula for copper bromide containing the CU plus ion?
The chemical formula for copper bromide containing the Cu+ ion is CuBr. This compound consists of a copper cation with a +1 charge (Cu+) and a bromide anion with a -1 charge (Br-), thus requiring one atom of each element to balance the charges.
Is copper positively charged or negatively charged?
A copper ions has a positive charge, most commonly 2+.

What is the charge on the metal ion of the salt CuO?
The metal ion in CuO is copper (Cu) in the +2 oxidation state, since oxygen typically has a charge of -2 in compounds. Therefore, the metal ion (Cu) in CuO has a charge of +2.
What is the name of the ionic compound cu?
Copper(II) nitrate. The Roman numeral indicates the charge of the copper ion.
What is the chemical name of Cu Co3?
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.
What is copper's symbol in the periodic table?
The element copper (Cuprum in Latin) is symbolised by Cu
What is cupric cyanide tetra hydrate formula?
Cu(CN2) * 4H2O The Asterisk is a dot in most chemistry manuals. The Copper has a charge of +2 in the formula and the Cyanide (CN-) a -1. Cupric is for the higher charge of copper (+2), cuprous is for the lower charge (+1).
What is the charge on the copper iron cu3p?
The charge on copper ion (Cu^2+) and iron ion (Fe^3+) in the compound Cu3FeP would be +2 and +3 respectively.
On a periodic table what element is represented by the letters CU?
Copper (Cu) is the element represented by the letters CU on the periodic table. It is a metal with the atomic number 29.
