How did Mosley's work on atomic numbers show that atomic number is a fundamental property better than atomic weight??

With Moseley's contribution the Periodic Law can be restated: Similar properties recur periodically when elements are arranged according to increasing atomic number." Atomic numbers, not weights, determine the factor of chemical properties. please mark me brilliant

The number of electrons in turn is equal to the number of protons in the nucleus. Atomic number is a more fundamental property of an element than its atomic mass because when the elements are arranged in the increasing order of their atomic number, most of the defects of Mendeleev's classification get rectified.
In 1913 Henry G.J. Moseley did researched the X-Ray spectra of the elements and suggested that the energies of electron orbitals depend on the nuclear charge and the nuclear charges of atoms in the target, which is also known as anode, dictate the frequencies of emitted X-Rays. Moseley was able to tie the X-Ray frequencies to numbers equal to the nuclear charges, therefore showing the placement of the elements in Mendeleev's periodic table. The equation he used:
