- Sulphates contain both Sulphur and Oxygen atoms, hence, they contain two atoms, thus they are polyatomic.
- Sulphide are represented as
; containing only Sulphur atom, hence, they are mono atomic.
- Chlorides are represented as
; containing only chlorine atoms, hence, they are mono atomic.
- Nitrides are represented as
; containing only Nitrogen atom, hence, they are also mono atomic.
Therefore, sulphates are polyatomic as they contain more than one atom.
