The valences of copper are +1 and +2.
What is the valency of copper in copper sulphate?
Type your answer here... 2
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 formula for Copper(I) nitride?
The formula for copper(I) nitride is Cu3N. Nitride has a valency of -3
What is the name of CuCl2?
Copper Chloride

Why is copper Sulphate also written as copper II Sulphate?
Copper(II) sulphate is written like this because here II denotes the oxidation state of copper or in simple language, it denotes its valency.Copper sometimes shows +1 valency and sometimes +2.So to specify, its valency in a compound, the valency is written in brackets.
What is the formula for Copper(I) nitride?
The formula for copper(I) nitride is Cu3N. Nitride has a valency of -3
What is the name of CuCl2?
Copper Chloride
Why copper have 2 values?
It has two valency electrons in its outermost orbital.
What charge is copper 2 solphide?
Copper II sulphate has variable valency properties, which translates to variable charges.
What type of bond is II?
if you say copper(II) then it means that you are denoting a atom with +2 as valency. and copperIII) means u denote this atom with +3 as valency
Is copper disulphide a mixture or a compound?
Copper disulphide is a compound Assuming the coppers has valency 2 it will have the formula Cu(SO3)2
What is valency of cuprous?
"Cuprous" is an archaic term for what today is called copper (I), Cu+1.
How do you take out valency an element?
Group number 1 = Valency 1+group number 2 = valency 2+group number 3 = valency 3+group number 4 = valency 4+ and 4- (some cases) group number 5 = valency 3-group number 6 = valency 2-group number 7 = valency 1-group number 8 = valency 0For the transition elements they will either state Copper (III) Sulphate or it will be like Cu2(SO4)3You can find the valency by the base of sulphate and you know its positive because metals are always positive and are written in the left.Source: I am a GCE O Level Sciences Student (O2)
