Sodium chloride is composed of
Na+ ions and
Cl− ions. Now of course salt is neutral; and to ensure this sodium ion and chloride ions combine 1:1.
On the other hand, sulfur commonly forms an
S2− ion. (Sulfur is a Group VI atom, and its chemistry is similar to oxygen, which certainly forms the
O2−, oxide ion.) Since sodium sulfide is a neutral salt, each sulfide ion requires
2×Na+ ions.
