Why does iron have an abnormally high ionization energy?

Why does Iron have an abnormally high ionization energy? First, I'm assuming your question is essentially why doesn't iron follow the general trend where ionization energy increases when moving across ...

Electron configuration of ionized Copper

This can be explained via the (slightly empirical) concepts of shielding. In the one-electron ion Cu$^{28+}$, orbitals with the same $n$ have the same energy (neglecting some small effects). Thus, the ...

Why do we only use the principal quantum number to calculate the energy of an electron in an H atom?

In the hydrogen atom, the energy of an electron depends only on the principal quantum number. But this is only true for the hydrogen atom. For all heavier atoms, the energy of an electron depends also ...
