Answer:
2nd ionization energy is higher than 1st ionization energy, 3rd is higher than 2nd, and so forth.
The first ionization energy is the energy it takes to remove an electron from a neutral atom.
The second ionization energy is the energy it takes to remove an electron from a 1+ ion.
The third ionization energy is the energy it takes to remove an electron from a 2+ Ion.
