Copper want to give up it's valence electrons, therefore it is a positive cation when ionized. Answers appear to be 1+ and 2+. Typically metals have positive ions. The charge of copper can be determined by evaluating the anion charge(s) and then solving the cation side.

What is the name for the compound Cu2O?
Copper (I) Oxide or Cuprous Oxide
What is the chemical formula for cuprous nitrate?
Actually, the answer Cu(NO3)2 is incorrect for cuprous nitrate. Cu(NO3)2 is in fact cupric nitrate. Cuprous nitrate is represented as CuNO3 alone.
What is the valency of silicate ion?
the valency of silicate ion is 4-
What is the valency of a sulphate ion?
The formula for a sulphate ion is SO42- so the valency of a sulphate ion is -2.
What is cuprous nitrate?
Cuprous nitrtate is copper(I) nitrate. CuNO3. The copper is in oxidation state '1' The more usual form is cupric nitrate that is copper(II)nitrate. Cu(NO3)2 The copper is in oxidation state '2'. NB THe 'cuprous/cupric' comes the Latin name for copper , which is 'cuprum'.
Does cuprous oxide have a charge?
I think cuprous oxide has a charge of 1+, while cupric oxide has a charge of 2+. Cupric oxide is also more stable than cuprous oxide.
What is difference between cupric and cuprous?
Cupric is used when copper is in a +2 oxidation state while cuprous is used when copper is in a +1 oxidation state.
What is the valency of cupper?
Its Valency = 2the formula being CuOThe copper donates two electrons to the oxygen and forms one ionic bond.Added:There are two copper oxides, differing in color:if it is black powder, then it is copper(II) oxide CuO (cupric, more common, as in the mineral 'tenoriet')if it is red powder, then it is copper(I) oxide Cu2O (cuprous oxide, as in mineral the 'cupriet' and it occurs in 'Benedict's test' on reducing sugars)
What is the role of Rochelle salt in the Fehling's reagent?
Fehling's solution is prepared just before use by mixing equal volumes of two previously prepared solutions, one containing about 70 grams cupric sulfate pentahydrate per liter of solution and the other containing about 350 grams Rochelle salt (potassium sodium tartrate tetrahydrate) and 100 grams sodium hydroxide per liter of solution. The cupric ion (complexed with tartrate ion) is reduced to cuprous ion by the aldehyde (which is oxidized) and precipitates as cuprous oxide (Cu2O). So the tartrate part of Rochelle salt is the key reactant. In the case of sodium citrate: the cupric ion (complexed with citrate ions) is reduced to cuprous ion by the aldehyde group (which is oxidized), and precipitates as cuprous oxide, Cu2O. Thus the citrate is key to the reaction.
What is valency of cuprous?
"Cuprous" is an archaic term for what today is called copper (I), Cu+1.
How many electrons does cuprous ion have?
a cuprous ion has 28 electrons.
What is the name for the compound Cu2O?
Copper (I) Oxide or Cuprous Oxide
What number is the positive charge in a cuprous ion?
The charge on cuprous ion is +2. It is written as Cu2+.
What is the chemical formula for cuprous nitrate?
Actually, the answer Cu(NO3)2 is incorrect for cuprous nitrate. Cu(NO3)2 is in fact cupric nitrate. Cuprous nitrate is represented as CuNO3 alone.
