Atomic Ions Ionization Energy Values Assessment: Interpolative Empirical Analysis

Key Points

• The aim is to propose a novel framework for assessing ionization energy values of atomic ions using interpolative methods.
• Developed a novel ionization energy set theory based on iso-protonic, iso-electronic, and iso-ionic sets.
• Utilized a computational algorithm to analyze twenty-five iso-electronic sets against nuclear charge.
• Employed the Lagrange method to estimate uncertainties for 162 unmeasured ionization energy values.
• The algorithm successfully interpolated 162 new ionization energy values with defined uncertainties.
• Strong correlation identified between effective atomic nuclear charge assessment and Slater's effective charge.
• The study indicates a relationship between calculated ionization energies and Pauling's electronegativity scale.
