Answer:
A chemical symbol denotes in short, a particular element or an atom of that element. Chemical reactions are easy to write with chemical symbols than having to write the lengthy chemical names. Many scientists have devised several methods to symbolic representation.
Valency is the combining capability of an element. In other words, the number of electrons which an atom can gain or share or lose when a chemical reaction takes place defines its valency. The classification of elements into monovalent, divalent and so on is made based on their valency. Molecules are formed to satisfy the valency of an atom.
