The periodic table's elements are represented by element symbols, which are one or two letter notations. By combining the symbols of the reactants, we may name the products of a chemical process. In chemistry, element symbols are the abbreviated names for atoms and molecules.
The periodic table has a total of 118 elements, although this does not imply that there are only 118 element symbols. Molecules and compounds are also represented by these symbols. Most molecules that you haven't seen before can be identified by their symbols if you know all of the periodic table signs.
