![]() To count the total number of atoms for formulas with polyatomic ions enclosed in parenthesis, use the subscript as a multiplier for each atom or number of atoms. The subscripts in a chemical equation is the number on the lower right-hand side of a chemical element that. Exit from a superscript with ( Insert Typesetting End Subexpression ): is a mnemonic for power, as in x2. ![]() Type a superscript with ( Insert Typesetting Superscript ). ![]() ![]() The formula Ca 3(PO 4) 2 represents a compound with the following: What Are Subscripts and Superscripts in Chemistry. On Desktop Enter subscripts and superscripts directly from the keyboard or using menu commands. Subscripts and superscripts are perhaps most often used in formulas, mathematical expressions, and specifications of chemical compounds and isotopes, but have many other uses as well. Polyatomic ions are enclosed in parenthesis followed by a subscript if more than one of the same ion exist in a chemical formula. Subscripts appear at or below the baseline, while superscripts are above. Polyatomic ions are discussed in more detail in section 5.5. \).Ĭertain groups of atoms are bonded together to form what is called a polyatomic ion that act as a single unit.
