If sulphur(S8) exist as a polyatomic molecule then how in this chemical equation Sulphur is shown as a monoatomic?

Dear student,

Sulphur is also present in elemental form, it is a yellow colour element. But the most stable form of sulphur is its polyatomic form (S8). 
This reaction is possible with both the elemental form and its polyatomic form also. The polyatomic reaction is as follows-
8 Fe (s) + S8 (s) ---------> 8 FeS

And in the elemental form, the reaction is as follows-
Fe + S -----> FeS
This is an example of a combination reaction.
