For example, neutral iron ($\ce{Fe^0}$) is listed as "Fe I", while the $\ce{Fe^3+}$ ion, often called iron(III), is listed as "Fe IV". | |

Though it can be explained qualitatively for the lighter elements with some finer arguments than merely comparing orbital energy levels via the aufbau principle, things start to get messy when $f$ (and eventually $g$) sublevels and strong relativistic effects are present. If I find the time, I may write up an answer, but for now I shall link this NIST webpage, which has very recent data on ground state electronic configurations of atoms and ions. Just type in an element and play around! Lots to see. | |
