If you remove electrons one at a time from a neutral Al, which IE do you expect to have a significantly large increase

If you remove electrons one at a time from a neutral Al, which IE do you expect to have a significantly large increase (as compared to the other increases).


Solutions

Expert Solution

IE or ionization energy is the amount of energy that is required to remove the electron from the outermost shell of an atom or ion.

Now the electron configuration Al is : 2 , 8 , 3 , so when one electron is removed from its neutral atoms , it results into Al+ ions and the number of electrons decrease to 12. These electrons are more tightly pulled by the positive nucleus as compared to the ones present in the neutral atoms. So the successive IE value increases.

So the first ionization energy of Al neutral atom is minimum and the third ionization energy is maximum (larger value).
