The importance of valency in forming chemical formulae lies in:
Determining how atoms of elements combine with each other
Valency is the combining capacity of an atom of an element.
Knowing the valency lets us predict in what ratio atoms of different elements combine, and therefore write correct chemical formulae for their compounds.
Hence, the answer is Determining how atoms of elements combine with each other.
