Rachel Maddiee Posted January 7, 2020 Share Posted January 7, 2020 (edited) Does this do a good job of naming the compound and explaining how I determined it? Step 1 Cation: Fe+3 Anion: O-2 Step 2 Iron has two oxidation numbers Fe+2 and Fe+3 The element iron (a transition metal) has an electron configuration of [Ar] 3d6 4s2 with atomic number 26. It has two electrons in its 4s orbital and 6 electrons in its 4d orbital. When iron loses the two 4s electrons, it attains a valency of +2. It can lose one of the paired electrons from the 3d subshell (which provides a more stable configuration), and it attains a valency of +3. Step 3 Fe2O3 = iron(III) oxide Edited January 7, 2020 by Rachel Maddiee Link to comment Share on other sites More sharing options...
