Writing Chemical Formulas
... Remember - subscripts of 1 are never written in a formula! Identify the oxidation number for the element making up each half (positive & negative) of the compound. Use the oxidation number (without the plus or minus) for each half as the subscript for the other half. Do not write a subscript of 1. R ...
