Chemical formula, any of several kinds of expressions of the composition or structure of chemical compounds. The forms commonly encountered are empirical, molecular, structural, and projection formulas. An empirical formula consists of symbols representi
Anempirical formula consists of symbols representingelementsin a compound, such as Na forsodiumand Cl forchlorine, and subscripts indicating the relative number ofatomsof each constituent element. (A subscript is not used, however, unless the number is more than one.) Thus,benzeneis represented by...
The molecule of an element can be represented using a chemical formula by stating the symbol of the single type of atom present in it, along with its count. For instance, the molecule of chlorine (Cl) has two atoms. Therefore, it is represented by the chemical formula Cl2. The molecule ...

Chemical formulae provide insight into the elements that constitute the molecules of a compound and also the ratio in which the atoms of these elements combine to form such molecules. For example, the chemical formula of water, which is H2O, suggests that two hydrogen atoms combine with one ...
