The aim is to assess whether Slater's Rules provide the best method for calculating effective nuclear charge (Zeff) for undergraduate chemistry courses.
Comparison of calculated Zeff values using Slater’s Rules and alternative methods.
Analysis of ionization energies across the periodic table.
Evaluation of the periodicity of various atomic properties.
Slater's Rules underestimate the shielding effect of s and p electrons.
Alternative approaches yield better fits for gas phase ionization energies.
Periodicity in ionization energy is less accurate when calculated with Slater’s Rules.
