Electron Configuration of Cations Valence e-s in highest n quantum number are lost first. When valence e-s have the same n, the e-s in the  highest  l quantum number are lost first. Section 4.2 Any engineer knows  the e-s  are NOT removed in the reverse order they came in.  Remove  valence p, then s, then d.
