+1 for copper in CuI or Cu2I2.
+1 in CuI or Cu2I2. +2 in CuI2.
+2 for Copper
+2 oxidation state for the Copper. -1 for the Chloride
zero
If the question is Cu2, then it is equivalent to Cu and the oxidation number for any element is zero. If the question is Cu2+, then the oxidation number is +2.
+1 in CuI or Cu2I2. +2 in CuI2.
+2 for Copper
+2 oxidation state for the Copper. -1 for the Chloride
zero
It has 3 main oxidation numbers.They are zero +1 and +2.
If the question is Cu2, then it is equivalent to Cu and the oxidation number for any element is zero. If the question is Cu2+, then the oxidation number is +2.
3+
+2 for Copper(II)
It depends on the compound. +1 and +2 are the more common ones (as in Cu2I2 and CuI2 respectively). In elemental form, its oxidation number is zero.
Copper Iodite
Oxidation number is the charge per atom in a compound. Cl2= 2- (Cl= 1-) Cu would have to be 2+ to balance the compound, because there is only one copper atom.
Copper oxidation is endothermic.
