This preview shows page 1 out of 4 pages. write down the substance table salt as NaCl. Describe the most obvious difference between the names in Model 3 and those in Model 2. No other ratios are possible since any other combination of ions in the compounds when you are naming their anion forms. The name 'iron selfie" could refer to either FeS or Fe2S3, so this name would not be sufficient. Fill in the table below using what you’ve learned from Model 3. Copper(II) Fluoride   Terms. Consider the ions of iron (Fe) and sulfur (S). In the compound zinc phosphide, what is the charge on the phosphide ion?
