How do we represent the constituent elements and their valencies in chemical formulas?

We represent them by writing the symbols of the elements and their respective valencies. For example, Na^+ and Cl^- for sodium chloride (NaCl).
In chemical formulas, we represent constituent elements by their chemical symbols and indicate their valencies as subscripts or superscripts to denote the number of atoms or charges respectively.
