Formula of Chemical Compounds
Chemical formula of a compound represents the elements present in the substance’s molecule in terms of their symbols. It is a description of its composition in which the chemical symbols indicate which elements are present and the subscripts indicate how many atoms of each element are present in one molecule.
Chemical formulas and elements found in several common molecular compounds are listed below.
