zinc sulfate
If the compound contains a polyatomic ion, simply name the ion.
When the compound contains at least two polyatomic ions of the same formula.
Polyatomic AnionOxigen. If a compound has name containing ending with -ite or -ate always contains Oxigen.-ite indicates three or less atoms in the compound. But it usually contain less than three oxigen atom.ex: SO3^2- sulfite ion, NO2- nitrite ion-ate indicates three or more oxigen atoms contained in the compoundex:ClO3- chlorate ion.Oxygen in the form of a polyatomic anion.
When the formula contains more than one unit of a polyatomic ion.
I think it is Sulfate SO4 2- But I could be wrong
If the compound contains a polyatomic ion, simply name the ion.
Polyatomic ion in the compound Na2O2 is known as peroxide. Such polyatomic ion contains two or more atoms covalently bonded.

it must be a compound of a polyatomic cation (i think ammonium might be the only one) and any polyatomic anion that contains no metals (sulfate, chlorate, carbonate, etc). Some examples would be (NH4)2SO4, (NH4)2CO3, etc.
Na2 is not a compound. When you see a formula containing Na2, it means the compound contains 2 Sodium ions.
Ionic bonds and also covalent bonds
A binary compound is a chemical compound made up solely of 2 elements, for example P2O5, Na2O KCl. (The bonding is not relevant- it could be covalent or ionic.)A polyatomic ion is a cation or anion that contains more than one atom. Most contain 2 different elements. For examplepolyatomic anions:- [SO4]2-, [NO3]-polyatomic cation:-[ NH4]+ , [Hg2]2+
The polyatomic ion in KNO3 (potassium nitrate) is NO3- , the nitrate ion. This ion is polyatomic because it contains four atoms bonded together. The nitrate ion is derived from nitric acid, HNO3.
