Here;s what I got.

The thing to remember about ionic compounds that have Roman numerals in their name is that these numerals represent the oxidation state of the metal cation. For iron(II) oxide, the #("II")# Roman numeral tells you that you're dealing with an iron cation that carries a #2+# charge. #"Fe"^(2+) -># the iron(II) cation The oxide anion is formed when an oxygen atom gains two electrons, which implies that it carries a #2-# charge. #"O"^(2-) -># the oxide anion Keep in mind that ionic compounds are neutral, so always look to have a perfect balance between the overall positive charge on the cation and the overall negative charge on the anion. In this case, you will have #["Fe"]^(2+) + ["O"]^(2-) -> "Fe"_ 2"O"_ 2# Therefore, you have #"FeO " -># iron(II) oxide For iron(II) oxide, the #("III")# Roman numeral tells you that the iron cation carries a #3+# charge. This time, you will have #["Fe"]^color(red)(3+) + ["O"]^color(blue)(2-) -> "Fe"_ color(blue)(2) "O"_ color(red)(3)# Therefore, you can say that #"Fe"_ 2"O"_ 3 -># iron(III) oxide For calcium sulfide, keep in mind that calcium forms #2+# cations and sulfur forms #2-# anions, which means that you will have #["Ca"]^(2+) * ["S"]^(2-) -> "Ca"_ 2"S"_ 2# Therefore, you can say that #"CaS " -># calcium sulfide For sodium chloride, keep in mind that sodium forms #1+# carions and chlorine forms #1-# anions, which means that you will have #["Na"]^(+) + ["Cl"]^(+) -> "Na"_ 1"Cl" _1# Therefore, you can say that #"NaCl " -># sodium chloride
