The charge of a copper ion is +2 ....>> or +1 (this is a more abundant oxidation state)
Added: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.
Copper normally is neutral but it can form ions with a 1+ or a 2+ charge.
When in ionic form, copper takes a charge of either 2+ or 1+.
+2 maybe ?
Copper there is 2 different types depending on the formula it is being used in:
it is either 2+ or 3+
Copper can have two possible charges, 1+ and 2+.
Charge of elemental copper (metal, Cu) is zero, neutral.
Ions of Cu can be either 1+ (cuprous, Cu(I)) or 2+ (cupric, Cu(II)).
+2!
2+
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.
Copper(II) ions are double positively charged (2+), while hydroxide ions (OH) are singly negatively charged (-1). There must be 2 hydroxide ions per copper ion in a neutrally charged ionic structure. Thus Cu(OH)2
It generally refers to Copper(II) nitrate: Cu(NO3)2
formula for Copper (I) is Cu- and the formula for Phosphate is (PO4)3- the two have to have a net charge of zero, but (Cu)-(PO4)3- is uneven +1+-3=-2 so adding 2 more Copper (I) to the compound the formula Cu3PO4 ends up as leaving the net charge to be 0 = +3 + -3
Cu, which is derived from the Latin word for copper, cuprum.
As (arsenic) has the 3- charge while Cu (copper) has a 1+ charge.
A copper ions has a positive charge, most commonly 2+.
Copper(II) nitrate. The Roman numeral indicates the charge of the copper ion.
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.
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).
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
Copper is one of the transitions metals that is known to form ions of different charges. Copper I is Cu+ with a single positive charge and Copper II is Cu2+ with two positive charges. The Roman numerals indicated the amount of positive charge for a transition metal.

on the periodic table,what element is represented by the letters ''cu''
Cu stands for copper in the periodic table.
Cu(2-) does not exist, because Cu does not gain electrons at all being a metal. When it gives off two electrons Cu(2+) ions are formed.
The element copper (Cuprum in Latin) is symbolised by Cu
