The valency of sulfate (SO4) is calculated by considering the individual valencies of the atoms that make up the ion. In sulfate, the sulfur atom has a valency of +6, and each oxygen atom has a valency of -2. Therefore, the overall valency of sulfate is -2, calculated as (+6) + 4(-2).
The valency of sulphite is 2-, meaning it has a charge of -2. The valency of sulfate is 2-, meaning it also has a charge of -2.
The sulfate ion (SO4 2-) has a valency of 2-. This means that it can form ionic bonds with other ions by gaining two electrons to achieve a full outer shell electron configuration.
The valency of copper in copper sulfate (CuSO4) is +2. This means that copper has a charge of +2 in this compound and it forms ionic bonds with the sulfate ion.
To calculate the valency of an element from its electronic configuration, determine the number of electrons in the outermost shell. The valency is typically the number of electrons needed to complete the outermost shell to achieve a stable octet (eight electrons). For example, elements in group 1 have a valency of 1, while elements in group 17 have a valency of 7.
There are two compounds , that are sulphates of iron. It depends on the oxidation state of the iron cation. Oxid'n state '2' ; Ferrous sulphate ;Iron(II) sulphate ; (FeSO4) (Pale green colour) Oxid'n state '3' ; Ferric sulphate ;Iron(III) sulphate ; (Fe2(SO4)3) (Brown colour).
The sulfate anion has a valency of 2-, i.e. it is SO4^2-
The valency of a sulfate ion is -2, meaning it has a charge of -2 due to the presence of four oxygen atoms and a sulfur atom. This valency allows the sulfate ion to form compounds with metals and other ions through ionic bonding.
The valency of hydrogen sulfate is -1. It has the chemical formula HSO4-.
The valency of sodium in sodium sulfate is +1, while the valency of sulfate is -2. Therefore, the valency of sodium sulfate as a whole is +2.
The valency of sulphite is 2-, meaning it has a charge of -2. The valency of sulfate is 2-, meaning it also has a charge of -2.
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.
Valency of k=1+ valency so4=2- after crisscrossing the valencies, we get- chemical formula- k2so4
The valency of magnesium in magnesium sulfate is +2, as magnesium typically forms ions with a charge of +2. Sulfate (SO4) has a valency of -2 because it usually gains two electrons to achieve a stable octet.
Copper II sulphate has variable valency properties, which translates to variable charges.
The valency of sulfur in ammonium sulfate is 6. This is because each sulfate ion (SO4^2-) contains one sulfur atom with a valency of 6 due to its ability to form 6 covalent bonds by accepting two electrons from each of the four oxygen atoms.
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)
