What happens to the successive ionization energies as more electrons are removed?

Question

a) the ionization energies level off after the second electron is removed
b) the ionization energies increase dramatically after the second electron has been removed
c) the ionization energies continue to increase a relatively steady amount with each electron removed
d) the ionization energies drop after the second electron is removed

Answer 1

c is true - until the last electron in the outer level is removed, anyway. Then there is a big increase.
