Iron and sulphur make iron sulphide
Iron(II) sulphide: FeS. Iron sulphide is a synonym, but the first expression is more correct. Iron(III) sulphide: Fe2S3. Other forms of natural iron sulphides are known: see the link below.
If you mean, "What elements make up iron sulphide," then they are Iron and Sulphur. Various 'types' of iron sulphide exist, including FeS (iron (II) sulphide), FeS2 (commonly known as pyrite, iron (II) disulphide or fool's gold), and Fe2S3 (iron (III) sulphide).
The two possible formulaunits for Iron Sulfide are; FeS, and Fe1S1
iron sulphide is FeS while rust is oxide of iron Fe2O3.
iron sulphide, iron(II) sulphide or ferrous sulphide. Iron sulphide is ambiguous however and could refer to any one of a range of iron sulphur compounds,including Fe3S4 and Fe2S3
