Succesive Ionization Energies
Patterns in removing multiple electrons HW 8-16
2
Ionization Energy – energy required to remove an electron from a gas phase atom
IE1 -First Ionization energy – energy required to remove 1st electron IE2- 2nd Ionization energy– energy required to remove 2nd electron IE3- 3rd Ionization energy– energy required to remove 3rd electron Successive Ionization Energy Always Increases – it is harder to remove each additional electron IE3 > IE2 > IE1 X → X+1 + e- X+1 → X+2 + e- X+2 → X+3 + e-

Filled Valence Electron Energy Level = Very Stable
“Easy” (less energy) to remove valence electrons Remove e- from a filled valence electron level = LARGE ENERGY INPUT REQUIRED (disrupting very stable arrangement) In your coursebook at the top of 8-16 sketch the rough pattern that you would expect to see for successive ionization energies for Al, #13.
