Solution

Valency is defined as the combining capacity of an element.
The formula of a compound can be written by exchanging the valencies (cross-over ).
Since the valency of carbon is 4 and that of sulphur is 2.
Therefore, the expected formula is $C_{2} S_{4}$ or ${CS}_{2}$ .
The compound is called Carbon disulphide.
