The Ionization energy computed as per nuclear theory is 720KJ/mol.
Given - Ionization Energy is 2.18 x 10⁻¹⁸J.
The main aim of the question is to find the Ionization energy with units KJ/mol.
The amount of energy to eject an electron from ground state to infinity is ionization energy.
[tex]x= \lim_{n \to \infty} disintegration[/tex]
Disintegration refers to the removal of electron via various methods .
one of the famous methos is photoelectric effect.
Using photo tubes is an option.
vacuum tubes and diodes also is an aid to remove atoms but can disrupt the atomic structure. So X rays are crucial part to this process.
So, the enthalpy required for this min 720KJ/mol.
