The oxidation number of the polyatomic ion sulfate (SO4) is -2. Each oxygen atom contributes -2, and since sulfate has a charge of -2, the single sulfur atom must have an oxidation number of +6 to balance the charges.

How to solve for the oxidation number of charge of a polyatomic ion?

To find the oxidation number or charge of a polyatomic ion, consider the known charges of the individual atoms within the ion. For example, in the sulfate ion (SO4)2-, oxygen typically has an oxidation number of -2, and sulfur would then have an oxidation number to balance the charge of the ion. The sum of the oxidation numbers of all the atoms in the ion should equal the overall charge of the ion.


What portion of the compound magnesium sulfate mgso4 is a convalently bounded polyatomic ion?

The sulfate ion (SO42-) is the polyatomic ion


What is the formula for the polyatomic ion SO5?

The polyatomic ion SO5 does not exist. The closest polyatomic ion to this is SO4^2- which is called sulfate ion.


What compound is composed of a metal plus polyatomic ion?

An example of a compound composed of a metal and a polyatomic ion is magnesium sulfate (MgSO4). In this compound, magnesium is the metal, and the sulfate ion (SO4) is the polyatomic ion.


Name Na subscript 2 So subscript 4?

Na2 SO4? - SO4 is a polyatomic ion with a charge of -2. It is Sulfate. When you have a polyatomic after the first element, you do nothing to change the ending of the polyatomic ion. Since Na has an oxidation number of +1, Na2 creates a +2 which balances out with the -2 of sulfate. So, the name would be Sodium Sulfate. (Again, you do nothing with the ending of a Polyatomic | don't add an -ide at the end.Sodium Sulfate...

What portion of the compound copper sulfateCuSO4 is covalently bonded polyatomic ion?

In copper sulfate (CuSO4), the polyatomic ion is SO4^2-, which is covalently bonded. The copper ion (Cu) is not part of the polyatomic ion and is ionically bonded to the sulfate ion.


Does MgSO4 contain polyatomic ions?

Yes. Mg2+ is a monatomic ion, but SO42- is a polyatomic ion composed of two elements, sulfur and oxygen.


In Chemistry what is SO4-2?

SO4-2 is the sulfate ion, which consists of one sulfur atom bonded to four oxygen atoms and has a charge of -2. It is a common polyatomic ion found in many compounds, such as in salts like sodium sulfate.


What is the oxidation number of sulfur in aluminium sulfate?

The oxidation number of sulfur in aluminum sulfate is +6. This is because each oxygen atom has an oxidation number of -2, and there are four oxygen atoms in the sulfate ion (SO4). The overall charge of the sulfate ion is -2, so the oxidation number of sulfur must be +6 to balance the charge.


Name the polyatomic ion SO42?

SO4-2The sulfate ion is a polyatomic ion made up of one sulfur atom and four oxygen atoms, that exists only if it can gain 2 electrons (from some metal cation or cations). It has a charge of -2. Note that this is the sulfate ion and not the sulfiteion.
