SUMMARY
The forum discussion centers on the anomaly in the order of increasing nuclear charge and atomic weight, specifically highlighting Argon (atomic number 18) and Potassium (atomic number 19) as the exception. Brian L. Silver's assertion in "The Ascent of Science" is confirmed, noting that while the order generally aligns, Argon's most common isotope has 40 nucleons, contrasting with Potassium's most common isotope, which has 39 nucleons. This discrepancy illustrates the complexities of isotopic variations in elemental classification.
