How does sulfate and sulfite differ? - Quora

Sulfide is also an anion with a net -2 charge, but it is not a polyatomic ion, "it's an inorganic anion of sulfur." The net charge on the sulfide anion, unlike the sulfate anion, comes from elemental sulfur gaining two electrons to fill its octet, as a result of this, it gains a net negative charge.
