Web7 apr. 2024 · The basic equation of Ionization energy is written as: X → X+ + e- Once the electrons are removed from the atom or molecule, the amount of energy required to remove other electrons from the same atom or molecule. Thus, the equation changes. Equation changes, as the amount of energy required to remove electrons, is changed. Web28 jan. 2024 · Which has more ionization enthalpy copper or zinc? The first ionization enthalpy of zinc is higher because it represents an ionization from the 4s level. Now zinc does have an ionization enthalpy of 906 kJ/mol, which is higher than copper’s 745 kJ/mol or nickel’s 736 kJ/mol in the same series.
