Binary+Ionic+(with+multi-charge+cation)

A binary ionic compound (with multi-charge cation)is composed of ions of two different elements, one of which is a metal, and the other a nonmetal, and of which the metal is a metal with multiple positive charges

The rule for writting the chemical name for binary ionic compounds are: 1. the positive ion, or the cation, is to be named first [Iron] 2. the cation name remains the same [Iron] 3. the cation's charge is to be displayed by writting the Roman numeral after the cation's name [Iron(III)] 3. the negative ion, or the anion, is to be named second [Iron(III) Iodine] 4. the end of the anion name has to be replaced with -ide [Iron(III) Iodide]

The rules for writting the formula for binary ionic compounds are: 1. the chemical symbol for each ion is to be written the way it is [FeI] 2. the number of each individual ion is to be written on the bottom right corner of each individual ion [FeI3]
