Chemical formulas are more limiting than chemical names and stuctural formulas.The simplest types of chemical formulas are called empirical formulas, which use only letters and numbers indicating atomic proportional ratios. Although a chemical formula may imply certain simple chemical structures, it is not the same as a full chemical structural formula. A chemical formula is not a chemical name, and it contains no words. These are limited to a single typographic line of symbols, which may include subscripts and superscripts. A chemical formula is a way of expressing information about the proportions of atoms that constitute a particular chemical compound, using a single line of chemical element symbols, numbers, and sometimes also other symbols, such as parentheses, dashes, brackets, and plus and minus signs.
