In the process of ionization, what is the relationship between the second ionization energy (i2) and the third ionization energy (i3)?

The first ionization energy is the energy that is required in order to remove the first electron from an atom in the gas phase, the second ionization energy is the energy required to remove the second electron from an atom in the gas phase. ionization energy will generally increase for every electron that is removed and increases from left to right in the periodic table and moving up the periods

A.(nh4)(2co3)is the correct answer
