Steps to writing chemical formulas. 1. Write the symbols; Most chemical compounds have two names. The first name is the cation (positive ion) and the second name is the anion (negative ion). In a binary compound, the first name will be a metal ion. The second name will be a nonmetal ion. In a ternary compound, the first name will be a metal ion with the exception of ammonium. The second name.
