To determine

Introduction:

Elements combine together to form chemical compounds. The chemical formula for the compounds formed depends upon the valency or the charge on the elements that are combining together in the reaction.

The notation for a chemical compound describes the number of atoms of each element, which is indicated by a subscript written after the symbol for the element. By convention, no subscript is written in the formula when a molecule contains a single atom of an element.
