To complete the statements, we need to understand the composition of ammonium sulfate and the nature of its ions.
1. The compound ammonium sulfate ([tex]$({NH_4})_2SO_4$[/tex]) consists of two types of ions:
- Ammonium ion ([tex]$NH_4^+$[/tex])
- Sulfate ion ([tex]$SO_4^{2-}$[/tex])
Both of these ions are not single atoms but collections of atoms. Such ions are known as polyatomic ions.
2. The ammonium sulfate molecule itself consists of:
- Two ammonium ions ([tex]$NH_4^+$[/tex])
- One sulfate ion ([tex]$SO_4^{2-}$[/tex])
Now, let’s fill these into the drop-down menus:
1. The compound ammonium sulfate consists of two ions, [tex]$NH_4^+$[/tex] and [tex]$SO_4^{2-}$[/tex], both of which are polyatomic ions.
2. A molecule of the compound consists of 2 [tex]$NH_4^+$[/tex] ion(s) and 1 [tex]$SO_4^{2-}$[/tex] ion(s).
