SWhat changed
Moseley measured characteristic X-ray spectra and showed that their frequencies follow an approximately regular relation to element number, providing physical evidence for ordering elements by atomic number rather than atomic weight.
Scientific scope
Moseley measured characteristic X-ray spectra and showed that their frequencies follow an approximately regular relation to element number, providing physical evidence for ordering elements by atomic number rather than atomic weight. The reported frequency/atomic-number relation concerns the measured characteristic X-ray series and historical atomic model. It is not a complete modern quantum derivation or proof of every elemental property. Sample coverage, instrumental limits and later interpretation remain distinct. The two reports form the stated contribution lineage rather than independent duplicate awards.
