it is a salt of two polyatomic ammonium ions and one polyatomic sulfate ion.

it is a mixture of three polyatomic ammonium ions and a polyatomic sulfate ion.

it is a mixture of two monatomic nitrogen and hydrogen ions and one polyatomic sulfate ion.

it is a salt of monatomic nitrogen, hydrogen, sulfur, and oxygen ions.

It is a salt of two polyatomic ammonium ions and one polyatomic sulfate ion

Explanation:

Ammonium Sulfate is an ionic compound formed by two polyatomic ions, Ammonium NH+4 and Sulfate SO−4 . ... Therefore, it will take two +1 ammonium ions to balance the one -2 sulfate ion. This will make the formula for Ammonium Sulfate (NH4)2SO4
