FREE Expert Solution

We’re being asked to name Fe2S3. The rules for naming binary ionic compounds are as follows:


1. The metal keeps its name, and is named and written first.

– For transition metals, we use Roman numerals to denote its charge.


2. The nonmetal keeps its base name but has its ending change to –ide.


We can see that the metal in the ionic compound is Fe (iron), which is a transition metal. This means it has many possible charges.
