So Na+. So the sodium atom has equal numbers of protons and electrons. But the sodium ion, we've lost one of those electrons. Right so we're going to lose this outer electron here. Right so the sodium ion has this for an electron configuration. 1s2, 2s2, 2p6. And so we lose this one electron. Notice for the ion now we have all paired electrons.

Many compounds are paramagnetic. Electron Configurations Example V: [Ar]4s23d3 Fe: [Ar]4s23d6 Exceptions: Cr and Cu Cr: [Ar]4s13d5 Cu: [Ar]4s13d10 Electron Configurations First-row transition metal ions do not have 4s electrons. Energy of the 3d orbitals is less than that of the 4s orbital. So Transition metals lose s-electrons before d-electrons. So that would be good to know especially for these ions. If we wrote this out, it would be 1s2, 2s2, 2p6, 3s2, 3p6. And since we're taking away two electrons, because it's 2+, we'll omit the 4s2 electrons, and we'll just write 3d2. So basically the 4s-electrons are taken away.
Fe atoms lose two electrons, so they are oxidized to Fe2+ ions.
